Rewards For Loyalty

I was going through my ranked history and i never really thought about it before but i have been playing League of Legends for 6 years !. granted its not the longest time in the world but its still a fair amount of time to be playing one game, so i got to thinking and i came up with the idea of a ranking system on rewards for people who have been playing the game for a certain amount of time. for example if you were a beta tester you could get a skin or some RP, from season 1 a medal and so on. i think it would give us players a nice change knowing that we have got rewarded for our loyalty, after all it can become like a routine playing the same game over and over for 6 years and yet i still find myself enjoying playing League after all this time. Just a thought for riot to think about, i know that we have got rewards for our good behavior and things like that but what about the dedication of the players who don't quit and who keep playing after all this time...you never know :)
