They could always stack the runes instead of having them take 1 slot in your inventory.
Yup, and have a Dropbox when you hover over them...
But why? Only action you can take on the charged Runes is to discard them.
A dropbox, similar to what your gear does currently. I have 4 runes, some at different stages of charge. If the item is stacked and I hover over the icon, a box drops displaying all of them...
Ah, you are talking about uncharged Runes. I was only talking about charged Runes.
