make dodge penalty worse
they need to make the penalty for dodging something more. more lp loss/mmr for each game you dodge making people who abuse the dodge system punished for making games take too long to start/fake win rates.
It takes usually 5-20 minutes to start a game which is quite ridiculous. This is a big issue in high elo, where people are scewing winrate. It's just insane getting 3-5 queues and it takes this long to make a game.
