Just stop playing this game for a while
The game sucks balls right now, go play Dota or PUBG
Yea sure you are giving Riot data to make balance changes when you play, but why should you? You are doing their work for free when you have no obligation to.
Stop playing this game, let Riot play their game to see what's wrong with it.
If you continue playing this game and continue giving Riot revenue, you aren't doing what Riot needs which is a fire under their ass so that they actually start testing this crap before they release it.
