Yeah. There are few times that I've actually dodged, but I only do it if I am fairly certain the experience was going to be a pain in the ass.
Last time I dodged was after a previous game with a certain player. I was Nidalee and he was Fizz. He claimed I kept intentionally healing the rest of team and not him, probably because I was mainly healing Shen who was actually going in and dealing damage. I told Fizz he was just imagining it, but that only inspired him to rage for the next two games. He was one of the worst Fizz I have ever seen. He would dive like crazy and barely even attack and suicide. And he trash talked me all game saying he will report me for trolling and shit.
Then he appears in the next game and says 'I should dodge for your in game trolling last game'.
Then I say 'You are the only troll. You dove without our team, killed yourself, and raged for no reason when you were practically useless to our team, there is no way I'm playing with you again.' and then I dodged.
It's one thing that he was a terrible Fizz, I don't care about that, but to rage and blame others the entire game when you are pretty much feeding the other team and not doing shit for our team is a whole nother story.
There is little enjoyment out of playing this game when idiots like that fill up your chat screen with their blaming raging nonsense the whole game, and if I have to get punished by LeaverBuster for avoiding a game like that then I don't mind the punishment.
