Now that some of the stuff we get access to has been revealed, I can say that I’m excited for a lot of what they’ve come up with; Idols in the later rows especially look interesting, and an actual reason to use Mind Flay in Monomania: Masochism is back, no/low cooldown on Mind Blast?, and we all get access to Disc Mind Blast that prevents damage, etc. One thing I’m a little skeptical about is, unless I’m misunderstanding something, we have to pick Mind Sear to gain access to Silence, Dispersion and Psychic Horror, not sure how that fits in, since it’s at least a few points pvp people pretty much have to spend, that pve can outright ignore. Also, if we don’t pick Devouring Plague is our insanity resource just dead? or perhaps we’ll be seeing some passive effects that interacts with the insanity bar.
But what are you all’s thoughts? Personally I’m excited to see what people put together with all these things.
