ARAM Rewards

I know a little while back Riot was talking about adding ARAM mastery and I assume thats still in the works but I also feel like the people who mainly play ARAM should also be given something for the amount of games they play or wins they have like an icon. Something along those lines would light a new fire for them to keep on playing ARAM. I fall into the group that mainly plays ARAM and I have over 6,000 games played of it and I feel like at some point people should be rewarded for the amount of games they play. It can also apply for people who play SR who play a lot of games on there.

Just a thought, feel free to add what you think could also be good rewards.
