(Bug) to many of the same role with a team of five

To be honest I would have thought that this was just a stupid little thing, but having encountered it every time I play, with someone accidentally picking another role someone else has in a team of five and a huge fight commences because they both have the same role. I really think this isn't a super necessary bug to fix, but it would be nice to make it so you can't select the same role again. I mean I even put it in queue, the whole team could be rolled as "support". Then it get's even crazier, look here: https://puu.sh/wDkq6/89be1778a3.jpg

I know right?! Absolutely insane, even the champion select does it. Anyways thought I would point this out to you guys so whenever you have some free time you can take a look at this little nuisance, thanks!
