You know what REALLY sucks about autofill?
You enter two non-Support roles (Top and Mid, for example), and you're prepared to get autofilled into Support. You get into a match, and the role you get put into is none of those three (Jungle, for example). If you're going to force me into playing Support, at least make me know what to expect. I suppose it doesn't mean Autofill as "automatically make you Support if your team doesn't already have one", it's "you're getting put in Fill, and you'll have no idea what to expect". Seriously, Riot? EDIT: You're also not guaranteed any roles even if you're not put in Autofill. Exactly the examples above, I put in for Top and Mid and made sure I wasn't put in Autofill (where it says "you're guaranteed one of your selected positions because you recently filled or played support"), and I got Jungle. You're not guaranteed shit in this game, and Riot is lying to you.
