Shorter Queue time suggesstion

I was thinking that it could shorten queue times if we had an option to select a third priority role that we don't mind playing. I personally can play Mid and Support best, but I also enjoy jungle and I wouldn't mind playing it in ranked.

So I just thought I'd suggest it and see what the thoughts are. The suggestion is, add a third option in the role select lobby that could be switched to off or any of the current options (top, bot, supp, etc.) This would allow persons who can/want to play any of 3 roles to get faster games and everyone should then benefit from these shorter queue times.

What do you guys think?
