Give the real developers back to WoW because these changes keep getting dumber and dumber with each patch. I don't know what interns you have replacing the senior developers but they clearly have no clue what they are doing. How many times are you going to fluctuate warrior/dk damage while you keep elemental shamans useless? Half the hunter glyphs don't work correctly but it's ok the tooltips are getting updated. Mages dominating 3v3, nerf moonkin. Honestly 95% of PTR changes seem to have come from darts to a dartboard.
Maybe make the PTR not just for show while you're at it hmmm?
