I have personally dodged queue. I hate doing it, but when you are looking at a team with 3 or 4 ad, no jungles, no support, and nobody willing to compose a team that is even competitive, then I am sorry, but yes I will dodge. There are times when you know the game is lost at champ select, and its not worth playing through and losing elo over.
I see your initial point, but if you are that worked up about it, then my suggestion would be to look for a 5s team, or play normal blind pick. The dodging comes with the territory of solo/duo queue. It really is as simple as that. And its a 15 minute ban for dodging ranked queues btw.
