Because things that cost money should never be a requirement. I don’t care if you can buy a phone for 50 cents, it’s an added cost that should not exist. You should not be able to call your game Free to Play if it isn’t. And a phone isn’t free, so neither is OW2.
Who cares about a sample size? It sucks for those players, it’s something they should not have to deal with. Especially legacy OW players who PAID for the game.
