Please make autofill optional.

I have been playing League since mid-season 4. Recently, I have had some bad experiences with autofill and would like to make a suggestion. I think autofill should be optional. Sometimes I want to wait a long time to get a role I want. If I want a quick queue time, I'll just play ARAM. About 99% of the time, autofill gives you support. And not everyone can play support very well (like me). I understand that autofill was created to reduce queue times for everybody and fill position shortages (support shortages) but if somebody really doesn't like support or really can't play support, they will be tilted all game, or troll, or just not do very well, thus affecting the entire outcome of the game. And nobody wants a tilted teammate, or a trolling teammate. And with someone like me, who doesn't get to play very often (like 3-4 games a week usually), if I really want to play a certain role that game, and I get stuck with support, I would be forced to either queue dodge, or try not to suck to much and it really takes the fun out of that match. And so I ask that we get some sort of option to turn on or off autofill for yourself or for your group.
