Good job Blizz... no acknowledgement for a bug that's actually preventing people from progressing. If there were actually people returning to the game or buying it new they'd be royally PO'd at your lack of a response to a known issue. Just imagine how much fun a new player would be having once they get to Maghda and can't progress at all because the FPS issue makes it virtually unplayable.
Keep responding to the bugs that don't really matter (like MP unticking), that can be worked around, that are at most annoying and are not in anyway, gamebreaking. -Claps hands- Well done.
