I didn't talk about flamming
I already play 2-3 qualify a day, I see some guys ruining games but not that much. Maybe you just play the bad ones, or me play the good ones ^^
The problem with consensus is that some players won't make any : for example a ranked game (not qualify) I played 1 week ago, a player didn't want to pause the game to wait for another one. That's not the topic but I try to say that there's a lot of players who don't have any fair play. Too much people took advantage of old kick system to kick good players or feeders too fast to get the leavers gold and ruin the game. You remember that for sure.
Some years ago I made a mistake when I wanted myself to kick a feeder in my team. I put the wrong number and started a kick vote against the bet player of our team. 100% of opposite team voted for the kick and we lost the game.
The fact is, I don't think developers can make a kick vote command for both team while counting only game sabotage reason, and all other reasons stay in each team to vote. I don't say it well but I think you get my idea.
It's just my opinion, I don't say I am true and you are wrong, just saying it
