No idea. However AS imps and nerfed nanoskills are why I have a sapph bow and not a tiger or a carbine (I still have a right hand symb). A choice I had to make and found a middle ground.
That of course wasn't due to pet casting reqs, but due to casting reqs on new malaise/DMW/speeches.
ANYWAY. I say nerf this thread, and all MPs/Crats/Engies unite to have a global agreement to make it so people who gank pets/debuff pets after you die, get stabbed in the face IRL.
