The raiding has me pretty interested. Even several of the mini-bosses are more compelling fights than most of the shit I did in modern WoW (late WotLK to MoP). I'm not entirely sure why... perhaps I just enjoy dodging red shit constantly. Also probably the model where they tons of mini-bosses mixed in with the regular bosses, so there's always something dropping loot around the next corner. We (SFA) are working on the Prototypes boss currently, and it's probably the least interesting of any of them for me so far (I really don't like council type fights), but it's still more entertaining than WoW.
