Yes. I've sat through horrible games just so I could report for champ select bullying. (Tried to steal my lane, banned my champ, spammed the missing ping the entire game, wouldn't let me farm, etc) Wasn't worth it.
I've dodged when the champ select was just that awful (anyone who says that slavery wasn't bad and throws out a bunch of racial and misogynist slurs as soon as they get into the lobby is not someone I want to spend a half hour with). The penalty was worth it to not have to play with those people.
I shouldn't have to sit through 20-40 minutes of awfulness just to report someone. And then because it was lobby stuff I have to hope that someone does a manual review.
I would take a system that would still give you a penalty for dodging as long as you got to report why you dodged. Just a simple pop up that asks if there was something in the lobby that should be reviewed for toxicity. Maybe if your report contributes to a ban you get 10 IP and any lost LP if it was a ranked game, it wouldn't be immediate so you couldn't game the system, only after a punishment has been made. But, again, being able to just dodge the lobby and know that a report was sent it would be good enough for me.
