I saw this on EU forums, and I would like to hear what people think on these forums.
I agree with the person who posted on the EU forums very much.

Should someone on your ignore list be blocked from being matched with you?
This would be an interesting way of punishing feeders/leavers/whiners and all other unpleasant people that we simply don't want to, and shouldn't have to deal with.

[Edit: I don't post too often on forums, so I'm not sure how to get this to be viewed by someone who could actually implement some change, so hopefully enough people will like this idea for it to get some attention]

oh def, it wouldn't completely fix MM but enough to make the game more enjoyable.

I think so too brokbaklgnd,

No one else has any feedback? :/

Its been on the backlog, but has severe queue time and MM issues. I don't know if its engineering or design time that it needs, but it is something Riot is considering

couldnt a top player just ignore all the competition and stomp all day?

ah well if it just keeps them off of YOUR team i approve this message.
