Let me conjure some examples

Player A: "OMG, those peoples are annoying! How dare they use the same name like me, Lina. I'm not hip anymore!"
Player B: "OMG, that male miqote looks cute. ME WANNA!!!'"
Player C: "Crap. This is bad. I accidentally kill my friend. I need to lay down. Oh, what to do, what to do. I know! I'll change my appearance and name. Now no one will catch me!"

All: "But I don't want to replay it all again!!!"

Yea, I guess thats called selfish


ps: I'm not against change. I'm against ridicoulous idea that will/potentially bring imbalance to either game mechanics, game experience and game lore. For those who said that I'm not role play enough, actually I role play enough. And right now, I'm role play as some adventurer in medievel setting, and to no friggin way access to some gender or even race change. Sure, I could dye my hair blond or black, but that? Totally not gonna happen in medieval setting
