Team Builder Incentives

Waiting for a Team Builder game sucks. Especially because, without fail, I am always waiting on a support and/or a marksman (If I haven't chosen to play one myself). As someone who likes fast queue times, I know I can jump into a TB game, pick support, and hop teams until I find a full one. Yes, if I am a support and TB puts me into a game that isn't full, I WILL move on almost instantaneously.

Riot already has the math to know which roles are most needed. Make an incentive for playing needed roles. IP, icon, I don't care. Just make sure it's only awarded after successful completion of the game. The role icons were a nice idea, but I saw plenty of people abuse those and the problem is still there.

Please guys, I get tired of playing support sometimes. And no, I won't wait the half hour it will take if I decide to queue mid.
