I like the proposed MCH changes a lot, though I wonder if they'd go through that much effort. Honestly, I'd appreciate them even changing the animations around a bit. Some of the only good/cool MCH animations are bound to Rend Mind and Foot Graze, which see almost no use. The main 2 abilities in our rotation, Slug Shot and Split Shot look almost exactly the same.
