League of legends community service.

I've come to notice that when coming in contact with people who were denied roles are more often than not unwilling to cooperate with their team. Autofill feels like a chore when going get into a game good behaviour is something that I feel is unappreciated when we are all veiled behind anonymity. Would it be possible for people who play fill/support regularly to receive minimal amount of rp? Why not reward the unsung heroes instead of forcing the unwilling into doing what they hate and consequently forcing more toxicity into the player base.
