They will just find something els to complain about. Its naive to think people will be satisfied with mirror games gone. Then they will complain about why his team get no healer options while enemy team got one. Or the usual leaving when people dont pick the heroes you want them to pick.
At this point nothing matters. Complainers will complain until everything has been removed.
Minorities want to decide what is best for the game while majority get what they like removed cause Blizzard cater to the loudest baby in the room.
