Hextech Crafting

I think there should be another way to obtain essence for hextech crafting besides disenchanting skins or champion shards. One way that they could implement this idea would be that you could disenchant your mastery 6 and mastery 7 level tokens. Mastery 6 would either give you 5 champion essence or cosmetic essence and mastery 7 would give you 10 essence for either (the type of essence would be random to fit with the theme of the hextech crafting system). I think this would be a positive step for the community and it would allow players to have something else to use the tokens for. If I can receive feedback on this idea I would really appreciate it.
