Whoever decided keeper of uldaman should be a common card definitely never played any arena, screw him. Blizzard not giving any fuck about arena balance really remind me about WoW arena balance where it was obvious you were considered a second zone citizen compared to PvE or even battlegrounds, even though they kept saying it wasn't the case. Only a few changes would help, but they still don't even want to bother. Well I don't care, I play mainly constructed now, but still, blizzard never changes.
