Blue Essence!!!

So I've been playing this game for a while, (a few years) and I have a lot of blue essence. Thing is, once you own all the champs, blue essence just pile up doing absolutely nothing.. Sometimes I change my name to confuse my friends but other than that, Blue Essence is USELESS*.* Can you make Blue Essence have more impact in the game? Because it feels like I get no reward for leveling up. All I get is money I cant use. [katarina-love] [cass-cry]
