After the comments of fellow players led me to finally write out some of my (rather useless) archery knowledge, I realized that a fellow archer had beaten me to the punch. Alas,
her guide is superior to mine. Perhaps the fact that I have some small information on ice manipulation might redeem me some.
Why, you ask, would anyone choose /ice for their already not-very-conventional archery/? Well, aside from Ice Patch and Build Up, no real reason. It just fit my character concept. However, one thing I did come to realize is having a largely useless secondary can actually be a
blessing. You see, you only have a few powers that you need to take, and then the rest is all up to you! Want to take that Jump Kick everyone says is lame, but you secretly want to see in practice? Go ahead! Have you always wanted to be invisible, but couldn't fit it on your ice/emp troller? Nothing's stopping you now! A refreshing change from kat/sr.*
I must also note that the forum would not allow my my true guide title in all its unadulterated glory, which was "Splendiferous! An Arrow/Ice Guide for the Discriminating Blaster". Therefore, I apologize to all non-discriminating blasters who were lured in under false pretenses.
And now, to the guide!
Archery!
My recommended slotting on everything is 3 dam, 2 acc, 1 recharge, except for rain, which is 3 dam, 1 acc, 2 recharge. However, if you don't regularly fight +3s and above, please feel free to disregard the whole 2 acc thing, I doubt you need it. In fact, get some end redux in there!
Snap Shot: The good thing about this power is that it's fast. The bad part is that it doesn't do much damage. Still, at lower levels, it's good for filling out your attack chain. I got it at level 4 because I had no choice, and subsequently ignored it.
Aimed Shot: Slower, but more damaging than Snap Shot. Get this as your first attack.
Fistful of Arrows: Mm. Not only does this have a cool animation, but you get to spray arrows in a nifty cone shape. Less range than airmed and Snap, though, so keep that in mind. Also, if you're only shooting at one baddie, said baddie will NOT get hit multiple times. Once per baddie in range. Still, it's great to have for groups, and you're also less likely to hit corpses. Score!
Flaming Arrow: Kind of slow to fire, so make sure your target isn't about to kick it before you fire off that button. On the plus side, this thing has some nice damage (and a little fire DoT as well). I'm not sure why it sounds like broken glass when you hit something. Maybe the arrow is made of...erm... burning glass >.>;;
Aim: This may sound crazy, but I don't use aim much. With build up, the time I have to use my attacks is short (add that to long arrow animation times, and you've got a winner :P). On the other hand, I put two acc in all my attacks. Try it out and see how it strikes you, but I'll stick with Build Up.
Explosive Arrow: A splosions! A targetted AoE with a chance to knockback, so be careful not to annoy tanks and scrappers by blowing away their targets too much. Correction: Be careful until you get Rain, and then who cares? Everything will be dead anyway >
Ranged Shot: It's your snipe! So much damage, and yet a chance to interrupted while using it, so don't use it in the heat of battle. I personally like the quiet singing sound it makes when it leaves your bow. Great for hunting. If your target survives, use your fire arrow on him. Not the other way around! Remember, interrupted = no shot.
Stunning Shot. Wow, a single target disorient? Pass.
Rain of Arrows. It's your nuke! Well, not exactly. You see, for the other powersets, nuke usually involves 1) some horrible endurance penalty, 2) really long recharge time, and 3) UBAR DAMAGE!!11elven. But Rain comes up every minute or so, acts like a normal attack in the case of endurance, and isn't necessarily going to annihilate everyone in in the area (although I guess you could say the same for any nuke). Sorry, no big explosions like Nova. So what's so great about it, you say? It sounds gimpy, you say?
Wrong.
Consider this: With two SOs, this puppy comes back even faster than my Build Up, which is 3-slotted for recharge. That's fast, son! You can pretty much use it on every group! Plus, no knockback and a steady supply of endurance left means... yes, that's right! Even after Rain hits, the poor surviving baddies are still tightly clustered! Time for MORE AOEs. My usual combo is Build Up + Rain, followed by Explosive Arrow, then, if there's anyone left, Fistful. Feel free to cackle madly while performing said combo >

.
So what's the downside? Well, there's really only one, and that's the activation time. It takes some time to load up all the arrows, shoot them, and have them all come down and inflict its delicious three tics of damage. So get just into range, wait for whoever's soaking up the damage to start running in, then sic Rain on the group. By the time whoever it is gets in and takes initial aggro, splendiferous arrowing is yours

. Even better is when you can team with a kin who has fulcrum shift. Stick close to them and wait..wait.. FS!
There were no survivors.
Ice Manipulation!
Chilblain[/i]. A single target immobilize. You have no choice but to get this. It's actually handy at lower levels to keep someone at bay while you arrow them from afar, but I wouldn't put any slots into it.
Frozen Fists. Er, no. As a general rule, things that make you put away your bow to use are more a hindrance than a help.
Ice Sword[/i]. A sword made of ice. LAME. Next.
Chilling Embrace. This is actually not bad if used correctly. It slows enemies who get up in your face.. but also causes some aggro. If you get it, remember to turn it off while travelling, or you'll catch some unwanted attention

. I dropped it, because once I got Rain, I found that no one really got close enough to me. Even if they did, Ice Patch means they won't be doing much to you anyways.
Build Up. Oh, man, this is nice. A brief buff that drastically increases your damage and increases your accuracy. Get it and slot it for recharge.
Ice Patch. Mm... this creates a patch of ice beneath you which slips up any earthbound baddies on it. Not as big as a troller's ice slick, but still mighty handy, because them slipping = you not getting hit. I would only slot this for recharge, but how much depends on how much patch you want. 1 SO basically lets you have a patch out all the time. Some patch strategy:
1) Stick it in a doorway, then stand outside and shoot to your heart's content. Laugh as they try to run after you and slip trying.
2) AoE, then patch. Those that come after you and try to punch your pretty face will be unable to

.
3) Get near a cluster of foes, then patch beneath them. This is good for getting some baddies off the back of a friend.
4) While running away, if things go bad: patch before running if you have time to slip up your pursuers.
Shiver. Never really used this one, honestly. It makes the baddies nice and angry, and although the slow is nice if used right, my primary job is damage.
Freezing Touch. Erm, maybe I'll pick this up for a Hami raid or something. Eventually.
Frozen Aura. I'm pretty disappointed with this one so far. You see, the baddies it DOES put to sleep can be awakened in the next hit. Even if I use it after I AoE as planned in order to get the remnants off my back, it's really not worth it. Other people quickly break them out of sleep. Lame.
Epic Power Pools! I've only really looked at Cold Mastery, but as you may be able to surmise from my ultimately planned build below, I plan on Force. Well, pick what you want, it's not like you don't have room for all 4 powers.
Snow Storm. This is a tough one. If it were available at a lower level, I'd say go for it; slows are delicious when you want to get trolls off your back. But by the time you can get it, you're already uber enough to kill the baddie you're anchoring on the next Rain. I loved it on my fire/cold corruptor... but that was because baddies would run away from my Rain of Fire and I wanted to keep them nice and ablaze. I guess it could be useful to slow tough enemies with lethal resistance... but you probably don't want a whole lot of those guys on your back, anyway. Hm.
Flash Freeze. As I understand, this is an upgraded version of Frozen Aura, which sucked mightily. Boo!
Frozen Armor. The best defense is a good offense. Plus, it's ugly, and gives you defense, not resistance. This means that people will hit you less often, but not less hard, which is cold comfort when you're faceplanted. But hey, if you've got the end, might as well give it a try.
Hibernate. Oh yeah, baby! When things get tough, the tough get encased in a chilly block of ice to recuperate. Of course, you can't do anything while encased in said ice, but you're also Not Dead. A toggle that lets you regenerate while not being affected by enemy attacks.
Those Other Power Pools!
Fitness . A must have! Pick whatever you want, but Stamina means you won't be gasping for air every fight. Mm...stamina.
Medicine . Some people will tell you not to bother with this pool, because defenders do it better than you. LIES. You want Aid Self, because you're a selfish jerk who wants to keep himself alive and not splatted on the ground. Slot that baby up for 3 heal and some interrupt duraction shortening. Aid Other is okay, I guess, and Resuscitate can be handy. Just don't go overboard with it, your job is to ARROW.
Speed . A lot of my friends like hasten. I don't, particularly, but it's better than Flurry, which not only makes you put away your bow, but sometimes ends with you punching away at the air while someone else has dropped your target. Super Speed's awesome, but you're going to need something for those high ledges, like jumping or hover. Either that or avoid Faultline. AT ALL COSTS.
Leaping . That's what I'm talking about! Acrobatics fixes that nasty knockback, and super jump is an uber fast way to travel. Combat Jumping's also nice for the bit of extra defense and as a mini travel power before you get SJ at 14. I wouldn't recommend Jump Kick, cause it means you're putting away the ol' bow.
Flight : Kind of nice, although flight is the slowest travel EVER. You can position yourself just so, and flight means you only get bowled over, not knocked back.
Concealment : I kinda like stealth, but here's the problem with invisibility and phase shift: you can't attack anyone while using it. This is not so bad if you want to use phase shift as a panic button or something and run away screaming, but invis can be a real pain. Plus, it suppresses now when you touch glowies, so what's the point? Alas, ninja are a dying breed. Grant invis, however, is nice because it gives invis to your teammates and they can still attack things (I don't really understand that logic, but okay).
Teleportation : Recall Friend is kinda nice to have just because, although it also means that morons will constantly ask you for tp. But I don't care for teleportation as a travel power, and tp foe? You have arrows, you don't need to tp to pull.
Times When People Will Ask For TP:
1) When you're not actually at the destination they want yet.
2) When you're obviously teleporting everyone on the team by going down the list, but haven't gotten to their name yet. Hey, look! Everyone on the team is slowly disappearing! That must mean I have to ask for tp EXTRA in case he forgets >

.
3) When they're 100 feet away from you.
4) When you don't actually have TP.
5) When you're dead.
Fighting : I've actually never taken anything from this pool, but Tough/Weave may be useful. Not sure if kick puts away your bow, but I'm pretty sure boxing does.
Leadership : Nah.
Presence: A blaster with taunt? HAHAHAHAHA.
Tips for Splendiferous Arrowing:
1) Don't shoot at things that are almost dead. Someone else will kill it first, and then you will be shooting a corpse.
2) Wait for your resident meat shields (tank, scrapper) to run in and grab aggro. Then, arrow. The acception to this is Rain (see way above), but you'll still be hitting them after said shield runs in, anyways.
3) If you're getting a lot of baddies after your squishy, squishy hide, try targetting through someone else. Click on them and you'll automatically target whatever they're targetting. No, don't target through the empathy defender, he's looking at another of your teammates! You don't want to shoot your friends, do you? Well, okay, but the game won't let you, so pick someone who's attacking.
4) If your friends are in trouble, try using Explosive arrow on their attackers. It's not guaranteed to work, but the knockback may disrupt the attackers and keep them from spamming your buddy to death before he can heal himself/get healed.
5) Don't Rain when your targets are all spread out unless you Absolutely Have To. The exception to this is soloing bees.
6) When soloing bees (The Swarm from Devouring Earth), they'll alternate between stinging you, and running off. The solution is to aim Rain at the ground right below your feet. By the time it goes off, a bunch of them should have come back TO THEIR DOOM. Pick off the rest >

. No one likes bees.
7) Watch your aggro in general at lower levels, as tanks aren't as good at keeping it yet.
So that's it. If you care to talk to me in game, my handle is Kuroda Yuuki, and I frequent Protector. Comments welcome.
