this is probably meme-build territory, but have you tried a team build to max out the effect/targets of the rit anniversary elite?
I have thought about it and I didnt like the idea. The weapons you will get are completely random and therefore have a very high chance of just being "meh" or straight up useless:p. Besides, to fully take advantage of the PvE Elite, you'd have to run a physical focused team that can be quite easily stopped by either: a lot of conditions, a lot of hexes, blocks, "general melee hate" (aka Shadow of Fear, Shared Burden, you name it). I dont know how well hero AI will use stance removals or whether they see it as just another attack skill. I know that foes use them as general attacks over using them as a stance removal.
