I've made a sonic/pain dom corr and that's it. I did sonic cause of the global resistance in PVP currently. I knew pain wouldn't be much new to me, but I've been wanting to make a villain emp for a long time. I'm tempted to make a shields brute or tank, but I'm not really a huge fan of the set. If I do make one, it will likely be a dark meleer, for the +end and heal powers. I'm tempted to make a PB now with all the new buffs to them and play around with a blapper build, but I have so many projects as it...
I'm really disappointed with the new sets. Pain is missing the biggest powers from empathy. Sheilds is a wierd blend of ninjitsu defense and some will power powers with a melee nova and a damage buff/target toggle throw into the mix. Between the two sets, there are only 3 or 4 actual new powers, the rest is recycled. It really sucks, cause dual blades and will power both had lots of new stuff to them. Dual blades might not be a great set, but it was still all new pretty much.
Spine, how many of those where not made on Virute?
