Loving the addition of more polymorphs and the return of some of our old ones. I didn't see pig or black cat there, though. And changes to priest shadowform: fantastic. It was just annoying having no control over it. Being stuck in shadowform even outside of combat doesn't make much sense from a lore POV, anyway. It also somewhat defeats the purpose of transmog.
All I want is for my voidwalker to not be stupid any more, or any of my regular pets for that matter. I just want them to stop running back to the last NPC killed and swatting it around while I'm dying trying to kill the one they're supposed to be helping me with. This has been a problem since I first started PTR months ago and was a problem mentioned in the forums months before I started PTR. It's a huge problem for us warlocks and it's not being addressed. I don't expect special powers or buffs like we used to have with the glyphs for our pets, I just want them to stop being dumb.
I need that amazingly sparkly bunny.
