Regen might be better with the resist to -regen it has now. Maybe though. My only 50 brute, until today, was staff/wp. Only thing that ever killed him was huge -regen debuff. Staff helped some with the +def attack though. WP was for sure better before. Like hands down no argument better. Maybe close now? I tried a tank with regen but deleted. Wasn't regen's fault I just didn't like the pairing I chose with it.
Made a brute instead that is MA/PSI and it is a lot of fun. The regen on it gets crazy high, speaking of regen. Haven't respec'd or played since I just hit 50. Stupid yard work. Aura of insanity is crazy good. Can't wait to get the hamis in it. Want to run an all PSI armor ITF and see how nuts it goes.
