new feature for hextech crafting idea

Had an idea that i think would be a great addition to loot and hextech crafting.

When re rolling 3 skin shards for a random skin permanent. If the skin you get from the roll is one you don't want then make it possible to revert it and get the 3 used shards back but make them unable to be used for any future re rolls. Since the chance of getting a legendary isnt all that high from re rolls anyway and you don't really get that many skin shards just from playing. This wouldn't hurt any money riot could make. People will of course check to see what they get and revert if they don't get a legendary for example but it may also prompt people to buy more chests from the store just to re roll.

It could mean slightly more money for riot but happier players that can still use their shards for essence.
