Nostalrius Begins - Quality wow vanilla realm (1.12)

I really, honestly don't think this will be an issue at all. Don't stress it. No one here has, or will.

To be honest, as goddamn stupid as a lot of Blizzard's management is, even they should understand that banning you for playing an older version of their game will do nothing but cost them a subscriber. They want your money.

You shouldn't care about your retail account so much .. I'm pretty sure you wont be caring about it as much once you get a taste of the nostalrius magic ! Welcome to the dream brother !
