Just become a support player.
No seriously, I'm tired of having people rage every game and complain that they can't support, or don't own any support champs, or threaten to afk/troll if they don't get a different role. It's obnoxious and annoying. So, I've decided to just start supporting in order to get rid of any chance of that happening now. And that's something odd, considering I main top/jg/mid, all damage roles. It's gotten so out of hand I have to give up what I prefer just to get a game where nobody is raging or trolling.
