Possible change for long-time players in the Hextech crafting system?

You do super well in game, get an s, and get a chest as a reward. You open it up in excitement only to find another champion shard inside. You own every single champion in the game, which just leads you to pile up more and more blue essence that you will never spend because there is nothing to spend it on.

I would suggest making the new skin chests the only things that drop for players who have taken the time to unlock every single champion in the game? I would think it would still be a balanced system granted the players who every champion have also played enough to unlock most of the chests on the champs they play already anyway.

All I know is I don't need more blue essence, and I sure as hell don't need anymore champion shards. at this rate I just bank 3 for the next new champ to come out.
