Enhancement Stone Conversion

You can trade 75 Gems for 1 Enhancement Stone. Why not let us have the ability to trade an Enhancement Stone for Gems?

Now I know 75 Gems per Stone trade in may be over doing it, but I'm sure everyone would be willing to take less Gems. There are a lot of us who no longer need the stones, whereas the Gems would be much more useful to us. Maybe like 25-50 per trade in, hell, I'm even willing to take 1 Gem per Stone trade in. This is just a suggestion myself and many others have been talking about recently.
