Show teammates' wanted roles in Champ Select

While not necessarily Riot's fault, you'll often find players in your games that got auto-filled or just really want to play their main role (or maybe the enemy first picked Yasuo and they can't lane vs him at all). However these players often won't even make the first step to trade with someone.

Why not show your teammates' wanted roles in champ select? Right now the power is 100% in the hands of the guy that got put in a bad spot. If you show everyone's role preferences, it at least creates the chance that someone who feels like it can suggest to bail someone out of his own free will. I know a friend of mine who mostly plays fill would love to be able to go "yo you want mid? I can play anywhere".
