Rewards for Supports

In rank queues - choose 'fill' or 'support' and you get a game almost instantly. Choose any other position and it can take up to 5 minutes depending on the time of day.

Given that support is the least popular position in ranked -AND- that support statistically has the lowest influence on a game compared to other champs in Bronze/Silver/Gold games; wouldn't it make sense to award something extra for supports?

Bonus LP on wins would make given the circumstances.
