I mean,a lot of the most hated features of the game are things the players asked for,such as LFR,endless grinds,titanforging,removing titanforging,pruning,unpruning,more focus on raids,less focus on raids (yeah there are a lot of things that were added and then removed because people whined),PvP templates,valor in its many forms,and then the lack of valor,garrisons....
The list goes on and on,almost every hated feature the game has had in the past decade and more were almost direct player requests
