Select more than 2 roles for ranked queue if you want

Hey Riot, I think it was a really great idea to choose roles before you queue. But what would make it twice as good is if you could select any number of roles you're down to play (2 minimum). This would probably help with the auto-fill problem too. I'm usually down to play 3 or 4 roles or even any. I love support, but I don't want to play it every game, but I know I'll get it if I choose is as one of my selections. I think it'd be really great if you could just keep choosing and ordering your role preferences all the way to 5, or just put 2 if you only like 2. Alternatively you could put a voluntary auto-fill feature where you still probably get your 2 roles, but you're way more likely to get filled than others. No one likes to play with a salty team mate, but a lot of people are down for some more variation in their lives.
