Dodge Punishments

Can we get a larger dodge punishment for frequent dodgers, like something that works like Leaverbuster and low-priority queue? Whenever new champs come out, or in ranked queues, I see this endless amount of dodgers (most of the time playing Yasuo and zed), and it really bugs me to know that they only have to wait 5 min. in queue before they can go to regular queue. I'm suggesting that a system is implemented in which after your first dodge, you don't get penalized, but everything after goes up from 1 min to 2 min to 5 min and so on, up to an hour, I guess. As well, if they dodge in ranked, they should get penalized in something like ending your promos, or getting reduced LP in your next few games.
