We need ingame kickvoting. We all know that. For those who don't (I suppose the devs who never play Quake, which are basically all of them), there are campers, teamkillers, whatever. Even people who just spec and tell peoples hp in CA to ruin the match.
So now I hope that you are convinced.
FYI, we need this in public servers too. Answers like 'go premium', or 'just join pro spawned servers', are no solutions.
