Live arena lvls' caps +-10
I suggest to create +-10 lvls' caps in live arena. I have 63 lvl account and I'm in 4th silver league, very often I meet there players 90+lvls (sometimes that's in 4/5 games) and that's almost all the time automatically loosing. That kills the mood to play at all.
With lvl caps game will become more friendly to new players and it will become more fun to play
