Well, it's not 'hurting' the game; I doubt anyone has quit because of it. But it is fucking annoying. Same goes for race changing, sometimes you just want a bit of change but it's just not worth the cost.
Just wish it was a bit cheaper, Blizzard's just being assholes with the price. I mean - If people will pay it, why wouldn't they charge that price? But still. Can buy a lot of games for the price of realm/race transferring lmfao.
