Hey friends ;]
my suggestion is very easy and short.
FIRST. Question- it is available to reset you stats?
SECOND(IF first no, then no talking about it). If im not happy with my stats, i can reset it. But not delete nick, just reset necessary stats- kills, deaths and ofc ratio. But save ability to save you money and ingame time. I guess this requires work, or not possible to do it ;] but if player not happy with his performance, he could reset. That's my suggestion.
Best Regards Friskyyy.!
