Low speed on leveling up / level 5051

Hello all.

While playing a match on last week, I found a player with level 5051. I reported him immediately, but I just don't know if somthing will be done about it.

Real feeling about this is total frustration. While some respect game standards of progression others just farm xp killing bots.

Would be nice of you guys if leveling progression could get a bit faster even when playing short matches. And also downgrade these player that have high ranks just because they found a breach on the game.

Thanks
