Force for a Tank-Mage 
But seriously, I'd say jump on the Test Server and have a little play about, see which one(s) fit thematically and to your playstyle.

Its kinda like.. what do you need, what do you want and what do you like 
Elec and Fire would suit your primairy hold power, making it a boss holder. Both come with a shield, elec having SL/elec and fire goes SL/fire/bitty-ice. As extra elec has a cone damage, not that high damage and needs position. Last is EMP, a massive aoe stun power that drains (3 endmod slotted) all min/lts and half boss end straight away. Also has -regen but only 15 secs. Recharge is pathtic long and you get a 10 second -recovery (no crash).
Fire goes Bonfire, wich you might know from /fire, a massive knockback thingie. Final is rise of the phoenix, quite fast recharge but not that great damage. Your private rez power so to call.
Force goes Temp.inv (duh), PFF (yeeey) and Force of Nature. This last baby hits (slotted) cap resist on SL (with TempInv) and high resist on the rest (ex psi) Its kinda like a 2 minutes i can punch whatever i like, since it has a good +recovery too. Crash however is annoying, full end drain. The final is Repulsion bubble, the most (imho) lousy power of APP's. A slow tick knockback that even highly slotted end-mod can drain your entire end in seconds.
Final, Ice. A SL def/ice resist shield (ok), snowstorm (a bitty high end AoE toggle that does -50% slow/recharge), very strong power. Then the target (big) AoE sleep power, wich i quite like but teamwise its really not usefull. Then the 'WOOOO' power, hibernate. 3 slotted recharge its up quite fast, you get 30sec (max) invurnarable (hmm..) and get high regen and recovery. Once done, you break free fully recovered. The master of panic powers.
Munition, ranged hold, ranged (big) aoe sleep, a passive SL (8%) shield and a target AoE snipe power. Downside.. redraw. (as 3 draw gun). The target AoE snipe is actualy quite strong, about 80%ish of a NRG snipe power. Does high knockback, longish recharge. I wouldnt recommend this if you are not AR, but only if you would like the snipe power.
So i dont know what your build is like, asume you drain masive on elec/ then run in to finish everything with some PBAoE /fire spammage. That line i would say elec, ice or energy.
Elec mainly due a good shield and the EMP, combined with elec/ it fully drains everything and does high -recovery. Compensate the -recovery with consume, mobs wont do much with EMP running. The ranged hold combined with elec/ hold for boss hold. Perhaps skip the cone power, do a run on Testserver if you might like it (as it has drain element).
Ice basicly due snowstorm and hibernate. Snowstorm can slowdown mobs massive (woo for slotted), add the def shield (okish) you can go melee a bit saver. Things go wrong? Pop hibernate.
Force.. ya well, Force of Nature basicly, your 2 minutes of glory. FoN crashed? Pop 1 blue and hit PFF, safe to get out without problems.
So run out to testserver, pick each set once and see what you like. Sometimes you need some extra slotting in it to make it fully usefull, but hope you get a ok view from this

How good is the cone from Elec Epic? Am thinking of taking it on my Ice/Fire for my second ranged AoE (Other than the always run Ice Storm) to go with Frost Breath. Slotting with some range

They were appropriately appalled
at the discovery of the eight victims
They're now putting it all together.
Women wrapped in silk

Eight legs, one body, silk,
spider, brilliant!"
The exact numbers i dont know but belive it was stated as 'moderate' damage, does seem to do a 2x damage. Surely with a BU/aim and a 2nd cone it will do pretty decent damage. The animation is the same as <whats the ladies name> temp summon from Croatoa. She holds her hands up, you see lightning going from her hards.

Wow. Thanks for taking your time to write all that! Really helpful, makes me see everything a bit clearer, now that I have a better description of the powers etc.
Now I noticed you said the Elec and Fire holds would suit as a primary hold power. Are they better than my current hold, Tesla Cage? Higher chance of successfully holding a target?
About the shields, are they good? Would they really be worth picking? Which brings me on to my next question, the cone attack that Elec has. I noticed on ParagonWiki it said Ranged(Cone) or something similar. Wouldn't that mean it is a cone attack I fire from a distance, like the Energy/ L6 attack?
When it comes to the L47 powers in these two epic pools, the EMP sounds really appealing. I am however wondering, is the damage good? And about how much endurance does it drain unslotted? And then there's the Rise of the Phoenix. Self-Rez sounds appealing, especially when I can use it if I fall in combat to get up to fight again, even if I'm in the middle of a group, and harming my enemies in the process. However, I usually play in teams, and usually have a healer/rezzer or more in the team.
Force. What can I say? To me it's really the least appealing of these pools, as when I go tanking, I don't really care if I die, and to me, that seems like the only thing it is for. Doubt I will be taking it.
Cold mastery.. You've managed to talk it back into consideration :P I had no idea the Snowstorm was that powerful, and the Hibernation sounds much more appealing now, when I found out the recharge wasn't that long after all.
Munitions. So I still will have to pull out an AR to throw a sleep grenade, eh? Hmm.. Waste of precious time.. The missile is still really appealing, but I realize that it might not be such a good idea going for that if the other powers are going to be so.. well, not useless, but not far from.
It would probably be easier to decide if I was level 50 (or 47), able to have all the powers, or at least the end power, in each of the pools.. But I guess I can just respec later.. Off to testserver for me to test on :P Still, more opinions and so on will be appreciated
I really like Elec (Hold, Smash/Lethal/Energy Shield [Energy Res good!], I skipped the cone and EMP because I don't think they're that good) for PvE, Flame is also pretty nice if you're a bit death prone, as Rise of the Phoenix is pretty handy.
Force (PFF and FoN) for PvP, and Ice is also good for PvP for Hibernate and Snow Storm.
Personally I'd go Elec, everything it does looks cooler than the other, bar maybe Rise of the Phoenix.

You like the word appealing is it?
The cone is indeed the same as nrg, or fire breath, or frost breath etc etc. The hold is a standard hold, it looks like the 2nd power from elec/ with a goodish DoT damage. The main reason for a 2nd hold, you can hold bosses (boss need 2x hold from a blaster).
Shields, iirc the numbers slotted:
Elec 20% SL/19% elec
Fire 20% SL/19% fire /8% ice.
Oh and EMP doesnt do any damage at all. It just is a massive long duration stun PBAoE. For comparing, a 3slotted version with PowerBoost (nrg secondair) can stun mobs in hollow long enough for me to go get a smoke, get a coffee and go toilet. When i got back... they still stunned.

Meh, I'm Norwegian, and it was the only word that came to mind that fitted correctly :P
And I went on test server yesterday, tried out a few of the skills..
Bonfire was actually pretty nice, as I could just stand in the middle if I was fighting melee mobs, and they'd continously (spelling?) run towards me and get knocked back, leaving me unharmed, while they die :P
Also tried the Elec Cone attack.. Has about the same damage as my Charged Bolts.. Requires me to be pretty close, though.. But you were right about me in the first post, I usually shoot at them a little from a distance first, and then run in for some PBAoE. So wouldn't the cone be useful on big groups if I'm in the middle there anyway?
Didn't really notice much of a difference with Snowstorm, but then I didn't fight any mobs around my level with it, and no big groups..
And the shields.. 20%? Really? Sounds like a fair bit.. Worth taking, then?
I another good thing about Bonfire is that if you cast in the middle of a group of robots they don't get knocked back, only knocked down and so it, in effect, becomes an AoE hold power.
Main Hero: Mazey - level 50 + 1 fire/fire/fire blaster.
Main Villain: Chained Bot - level 50 + 1 Robot/FF Mastermind.
BattleEngine - "And the prize for the most level headed response ever goes to Mazey"

I thought this worked like this only due to level difference?
Yup, if the mob has KB resist it does KD. If the mob is also reasonably higher level than you, again, it will do KD. If the mob is reasonably lower than you, it'll do pretty hefty KB.
Also Shields hit about the 30% mark, not 20% to S/L when slotted.
I am now a level 43 Elec/Fire Blaster, but I haven't levelled up since 40, because I just can't decide which APP to take.. They all have something appealing, but I've managed to (almost xP) decide to go for either Electrical Mastery or Munitions Mastery. Nothing is written in stone, though, because Flame still appeals quite a bit to me, and the others.. well.. could be good..
So, any advice? What are the pro's and con's with each of the APPs? Which is over-all best, or what is each pool good for?
I would be really grateful for some help..
