Nexon have gone back on a lot of promises.
I remember at the start they also said the game would be 'totally balanced' and there would be nothing you could buy with nx that you can with GP.
(TOTAL BS right now, isn't it?)
Anyway, a prestige system would be good, they could have like a number next to their GOA badge, etc (GOA 1, GOA 2) and when they reach a certain amount of exp they could get to GOA 5. Nice idea!
