See I think that is exactly the reason there should be penalties for dodging. Just because you don't like a pick that someone else chooses doesn't mean it isn't a solid pick. It would be incredibly frustrating for there to be a dodge every time someone didn't like a champion pick on their team or the opponents team, didn't like a ban, etc. Games in ranked would never start because someone would always be dodging because of something like this. And idk about you, but I think queue times are plenty long as is.
I thought that maybe one dodge per day would be acceptable, but someone correctly pointed out that it wouldn't really change much; the chance of getting someone who hadn't used their free dodge that day would still be very high and still lead to a large queue time.
