Need more things to do with all this materia

[Selvokaz]

I think we need a new option for materia use. You can slot tons of materia in armor and armor itself produces materia so for every two pieces you put into a single piece of armor, chances are you can get 3 pieces out of it before too long. I'm literally drowning in materia, from running quests, dungeons, and extracting it from gear, I have too much materia and not enough ways to get rid of it.

The market boards are of course my first thought but if I'm having this problem of an issue then other people are probably having the same problem. We need a way to expend it, and while giving it to the rebuilding efforts in Doma is one way to use it, there could be others.

Fusing it is too random and doesn't necessarily produce something of value.
So what else can we do with it? Perhaps use it as some form of currency in some new event, or to buy exclusive items from a vault?
