The New Crafting System

So the new crafting system came out and I did my first re-roll and I felt like there was something missing. The thing that I felt was missing is that whenever you re-roll you should also be able to earn a bit of essence too based on the champions you re-rolled. Like maybe a average of the essence you get from each skin shard. I don't know if this can be implemented, but I think players would like to earn some essence back from re-rolling.
