As it stands, it’s free to change your username in ToL.
Okay, yes I hate how ToS charges you $5 IRL to change your username, but it’s not just a moneygrab reason- well, not entirely. When you give people the ability to change their usernames, unlimited- for free, you open the gateways to massive nametrolling.
Anyways, my idea is simple,
make Name Changes cost a little bit of GP, even if not much- say like 250, or even 100 GP per name change. Just something.
