Hextech chests, Champ essence WHY!

out of the 20 chests or so that i have opened i have got more champs ( I OWN THEM ALL) then skins. How is riot going to deal with this i spend good money and time trying to get the damn thing to get items that i have no use for what so ever. Riot why are you trolling me with this chest crap. please give me at least a hint that i can use the ungodly amount of champ essence on something that I and every other summoner with all champs unlocked can do with
