OP’s take isn’t rational. People are paying a blizzard subscription for them to develop a game. When the game developers promise they’re listening to player feedback and say they’re developing content for WoW, then release a separate game mode that (as far as I’m aware) there hasn’t been demand from the player’s for and has very little to do with WoW other than using it as an engine and a few promotional rewards, it is absolutely reasonable to voice your displeasure and provide them with negative feedback as a customer.
