I don't know if people agree or not, but I belive that the Frozen Reinder Mount should be tradable ... I just don't see the pros or cons to having a mount be bound to your account.
NO NO NO, keep it bound to account.
This way those lazy people can't just buy one, and those level 9's who just happen to be there, but don't actually contribute to killing the dragon, can't get a massive windfall for it.
