Corruption Vendor

Does anyone else think Echoes of Nyalotha would work wonderfully as a currency to buy targeted curroptions? Im currently sitting, on my main, with around ~14k Echoes. I know its not the highest amount - but I cannot use them to buy any essence I dont already have.

It would be wonderful if, for example, I oculd buy rank 1 expedient for 1k, rank 2 for 3k, and then rank 3 for like... 5k echoes. Put the cost high enough for corruptions so that, every person wont be running infinite stars 10 at the cost of 1k echoes, but not too high that it takes 10 weeks to get 1 rank.

Just a thought.

Edit:/ I just learned that if you have all rank 3 essences, you don't earn Echoes. TIL! I think, that because it already exists in the game, and can be used to buy things from Mother, and that there is a system already in place to earn them - that it would be a good currency to use to purchase corruption. No need to add a new one - just fix it so that people who have all rank 3 essences can earn it.
