Your first dodge shouldn't result in a queue ban
It's very rare that people dodge once per 24 hours with malicious intent. Usually they have to do so because something unexpected happened in their real life, or (in the case of blind pick players) multiple people locked in the same role and have no way of backing out of it. I don't necessarily think that you shouldn't have ANY queue ban for your first dodge, but I think that ban should either be much lower or should start as soon as you dodge. (So when you come back from your IRL emergency you can hopefully get right back into League.)
