Hextech Crafting

For people who have every champ in game and still want to use the hextech crafting it's kinda like throwing money away when you get 5 champs out of 10 rolls. There's nothing for exchanging blue/yellow essences so basically we're screwed. Are you going to implement something where we can exchange essences or stopping the chance of getting a champ shard at all. If/when these changes go into effect will those of us who have champs/essences be refunded or some such thing. I want to continue to craft but last time i bought them i came out with 10 champs from 22 chests. I was pretty disappointed with losing that much money.
