I'm not up on the nerd terminology, but in the champion select screen, instead of forcing people into random teams with players that are toxic (and trolling people before a game even starts) and then imparting a 28 minute ban on them if they decide they don't want to play with some screaming, crying, psychotic gamer... Why not change the player select to allow a cohesive team to kick an obvious troll and make room for a player who actually wants to help? This would encourage people to work together, and be friendly, and all the little sick players who just want to log in and make the game miserable for others will have to play with EACH OTHER!
If I had $1 for every time I dodged a game because I knew I was about to play with a troll or an afker, someone bent on ruining the game for me and for others, I'd have all the skins I want. There are so many people who just love to ruin this game. Making this change would alter the community very quickly.
I know my thoughts will be ignored by Riot (because they don't give a ****) and by about 90% of the player/forum base (because they are all screaming, crying, psychotic gamer trolls), but maybe if enough people get on board with the idea and demand it, it could change how the game is played.
