I'm pretty interested in seeing the changes.
I'd love my enhancement Shaman to be a bit more fun as I actually preferred it during MOP. Sure the damage was all over the place especially with the quick attacks but I liked that - swinging her arms around all over the place. Nowadays that approach is more akin to my Fury Warrior.
I like curses back on Warlocks as character wise that was supposed to be Chepis expertise rather than demon summoning. Immolating thing as well.
