Idea: Premade Refusal (Matchmaking/Queuing option)

I just want to say that I enjoy the new champion select, and that I'm enjoying the game. For the most part, small premade parties (two or three players) are not an issue, and of course a five-man premade isn't a problem (or if it is, I just refuse to play with them again.)

But we've all seen them, we've all played with them. Those four-man premades that refuse to communicate in champion select, don't chat in ally chat, and have a tendency to not ping for anything (unless they're pissed at you for being the random). The first clue always being the dead silence, lack of chat, and sporadic pings. The second clue being that they don't listen to -your- pings. If you're lucky, this is all that's wrong. If you're not, they'll usually all flame you, or (sometimes) mass-report or try to convince the enemy team to report you.

So here's my proposal: a queuing option when you're selecting your roles that allows you to reject being matched with premades above a certain size. I'm sure that this will be a difficult sell, given Riot's push towards 'teamwork and premades', but it's so rare that I have a positive experience with four-man premades. Even the games that we win. Of course, coupled with the fact that the enemy team is usually more coordinated, it's an easy way to ruin a game for me.

Simply put, if there was a way to reject premade parties, it'd make the game feel a lot less toxic and a lot more enjoyable for me.

(I hope this is in the right place.)
