Just allow dodging. Dodging never hurts anyone anyways.
I know this sounds stupid but hear me out. Majority of the games I lose are not because of me. Most of the time Ill get a troll pick like zed jungle or janna bot, and i'm not even lying. Dodging helps but sometimes i just don't feel like dodging. The troll picks wont get my MMR and LP back. I feel like it is easier to climb in gold and plat than it is silver because they actually work together and dont pick ridiculous champions. Im not gonna use people being garbage as an excuse because it is a team game, but its the troll picks that bother me. Having to dodge 6+ games a day just because someone picks rengar mid is not okay. thats 50+ lp lost just because someone wants to pick a ridiculous champion for a lane. And even if you allow dodging, if someone dodges, its not hurting anybody..
