If they want to keep 3 bans, which honestly I think 3 is enough, I think it'd be cool if solo queue had the last 3 picks get 1 ban each instead of first pick getting all 3.
Mostly because first two picks both get their main role (if you only Main 1 role, please go to teambuilder). If I'm a late pick and tell you I want mid/jg/adc and the first 3 picks take those roles anyways so I'm stuck in an off-role, it would be nice if I could at least have banned a problem champion in that role or something. It's really sickening to see first pick take mid when 2 other people wanted it, to ban 3 mid laners, then still feed Lane hard. If you're first/second pick you really should never be feeding, you don't need to win Lane but at least be competent in the role...
Guess I sort of changed topic a bit, sorry.
