Blue Essence- Achievement System

Hey Community / Riot, Since many people complaining about the new BE system I had an idea. What if you (Riot) do some kind of achievement system (like wow, cod or other games) where you can unlock for example 500 BE and an "exclusive" icon (so that icons have a meaning) for killing 10 enemies with insert champion or kill 3 enemies on a different lane with 1 ezreal ultimate (just as an example). With this system people wich need BE can farm the achievements and people which don't need BE would have an additional end game, besides leveling, collecting the "exclusive" icons which you get from those achievements.

If this kind of System already exists I'm sorry, but I didn't recognise it because it is too "hidden", you could make an extra tab in the launcher and show the achievement which you might have earned at the end of a game. (Besides, I don't mean quests)

(I know it is a lot of work, but it would be, in my opinion, be very nice to have some alternative way of getting BE)
