New chest system punishes long term players

Ok. I was excited to see the new chest system where you can get loot for s rank. Only problem is i own all the champs and half of my chests are a waste because champion essence is 100% useless..... I have 40k IP and all champs. i don't need champ essence. A t least let me make it all orange essence. Please update. You shouldn't punish day 1 players who have the champs. I would love to buy some chests and even keys since i have like 6 chests and never get anymore keys after opening like 5 chests.... There is no point if 50% of my chests are useless champion essence. come on Rito. you have to see this as an issue from the start. Either you don't care or you only want to attract new players.
