I just wanted to say that your guides are very well written and laid out Welder, they are easy to read and to follow.
I also wanted to respond to the spn/reg build with some info of my own. I have a lvl 50 spn/reg scrapper named Crunch n Munch on the Freedom server that I think fits well into most scenarios I'd come across. I'll just say that spn/reg isn't the strongest choice for pve or pvp but it shines how well it can do both.
From a pve stand point, I always tried to build my scrapper to perform like an inv would in herding situations. Nothing is more impressive than herding 300 mobs and living to tell about it. Unfortunately I was never successful in reproducing what inv could do even at lower levels than my scrapper. I spent many hours using the test server and respecs to test various combinations of defense and resist powers to build the defense needed to overcome the damage intake of herded mobs. At one point, Crunch had stealth, tough, weave, resilience and combat jumping mostly slotted with defense or resist and hasten had one slot of def as well =P. This was at the cost of no fitness pool and heavy endurance issues...but I was on a mission to prove a point.
The result was being able to handle a few groups of reds...nothing like the inv that can handle mobs of purples. Keep in mind this is before integration regen was improved or fast healing was upgraded, epic pools didnt exist and no one had killed Hami on our server yet. So maybe with full Hami enhancements and overall regen being better than at that time, anything is possible.
For pvp, at this point I think it's a little too early to judge any AT in pvp prowess, but spn/reg seems to be hot and cold. Against anything but controllers and defenders, spn/reg is a killer. With the right power selections and slotting, spn/reg is basically a tank mage. Coupled with the body mastery pool, you'll never run out of end and acc isn't an issue. But the two ranged attacks in that pool combined with impale and throw spines...you're better than a blaster.
Like I said though, against trollers and fenders you're not so strong. Regen has no defense againt terror and a well slotted troller can hold you at will even without terror which is usually a certain death. Using just focused accuracy isn't enough against radiation or miasma fenders, you'll rarely hit them once you're toggled. Surprisingly, a dark/psi fender was able to kill me one on one recently without removing a single toggle of mine...that's some serious damage output. The only answer I can think of for fighting these two ATs is slotting your attacks with at least one acc maybe two, and running tactics. I say tactics because the other half of the answer is taking the dark epic pool and slotting petrifying gaze. I haven't tested this yet, but with enough acc in this power I think being able to hold someone in one on one...as a scrapper is unbeatable.
My critique on Warcupine's build only questions a few things, since it looks like a pve build. One thing I'd leave out is quills, simply because even with 6 dmg slots...the dmg to endurance ratio isn't worth having. When I had it, I also had to double slot it with endred, and with your two acc slots...that only leaves two dmg slots...which is hardly worth using, even with the slowing effect.
Some people may think this is crazy, but I opted to skip spine burst on Crunch after a few respecs. Reason being, the same reason as quills, the dmg/end ratio is bad. Spine burst is an end hog to use, and is very similar to throw spines in total dmg. The thing I like least about the attack is that it's pbaoe, which doesn't fit my playing style. Mob positioning is the key to efficiency, and usually that means having mobs tightly bunched in front of you. With buildup, throw spines, ripper and impale...I have all the dmg I need to quickly eliminate mobs. Since I skipped spine burst, I've noticed a nice difference in the end I use for pve.
The other question I have, at least for a pve build, is why have focused accuracy and slot each attack with acc? Once I took that power, I 6 slotted it with 3 endred and 3 tohit. This allowed me to 6 slot dmg in all my attacks...which is a noticeable difference.
Also, 6 recred in dull pain seems excessive since dull pain will only overlap for about 20-30 secs now. Those slots are better used in either buildup or more importantly...the reason you take body mastery....conserve power. Two or three slots in that is definitely a must.
Lastly, since spn/reg is an aoe guru...and having body mastery taken...I'd take energy torrent. It's a beautiful combo to have with throw spines since their cones are very similar. 6 slot it with dmg, it's quite potent and the knockdown is priceless for a regen scrapper.
That's all I have to comment on. Again, great build guides...that must have taken quite a bit of time! =)
