Champ select toxicity and legal dodging
If someone say steals a teammates champion intentionally, bans a teammates champion intentionally, and makes it very clear they're going to troll and you're in this for the long run, you should be able to somehow legally dodge. Especially in ranked. You're avoiding a bad situation before it starts. Being able to do a majority vote would be nice. So in Solo/Duo, if 3/5 players voted for a dodge, everyone would leave the champ select punishment free. It lets the troll go unscathed too which kinda sucks but at least they don't ruin a ranked game. Or something else I don't know, but being punished for this seems wrong.
I'm not defending dodging in general. I'm defending dodging troll players.
