I have a idea. This players who have a premium rank will don't have accses to join in Battlegrounds and Arenas, cuz they have more privilegs(prem menu, powerful items and etc.) And the simple player will down fast. :D
Is this possible?
hmmmmmmm yea dunno .... maybe you could try to interrupt it with an OnGossip event then check (if not premium return true), else (return false).
