We should be able to pick only one role
And then wait however long in queue for it. I don't care if I wait an hour. I play one role and one role only. Myself and my four other team mates are NOT going to have a fun game if I get put in a different role. Period. Riot, you're literally messing up the fun for myself and four other people every time I wait ten minutes in queue and then get forced into my off role because I am going to feed and we are going to lose. I mean, why even ask me what role I want to play when you never give it to me anyway?
One role - wait however long needs to be an option.
