This idea has been discussed before with no real response from SMG. They made another forum "Looking for Games" with the idea that this would allow high ranking players to find other high ranking players but nobody uses it because it didn't even come close to addressing the problem. The fraction of players who use this forum seems pretty small to me. An in game rank filter would make this game loads better.

Looks like SMG is including a rank filter in the next update!
FUCheaters
There is a little worse than having to deal with a Novice in a game. They are either used by cheaters in collaboration or attack in completely irrational ways, ruining the game. Is there a way to set up a game and bar certain player levels?
