There really should be a ranking system for Sparrers and maybe PKers.
BUT it is necessary to take tougher action against booster.
Like reset there stats, have a list where every booster is written on and maybe jail or bann them :/.
Moreover the stats should be resetable and every new player should get the chance to be on top of ranking.
I would prefer to do tournaments. Tournaments would be the only way to get points. So youre still able to train. Additionally that would be one way how to make there wont be boosters.
In my opinion there should be 2 different types of spar arenas(, SO THERE WOULD BE 2 DIFFERENT RANKING SYSTEMS TOO). PC Arena (like in 16-Man)
And iPhone Arena (like underground and basement [so iphone noobs'd be able to spar too])
