I don't see wPvP as wintrading in vanilla. Very hard to pull off getting GM/HW in Ungoro from farming. 
 
	 
 
	About the whole sheep thing, I agree it's a dick move and griefing. If you're not a warlock, it's hard to make sure the mob doesn't stay sheeped. That being said, make friends with warlocks and others, take a group there, and have fun kicking ass.
 
	Other than that, this will be a thing of the past when ZG releases.
