Played against a lvl 91 pro and a lvl 86 hack the other day in alt shot all with the best of gear they could buy.
They weren't cheating they just never played ranked games.
Most of the time this is the case, but, it's easy to tell who is trying to take advantage of the system and who isn't.
Personally i'd like to see clubs having tier restrictions aswell as level restrictions.
That may sound elitist in a way or people might say well it's allright for you to say that, but i know plenty of people will agree with me.
