Guild Wars 2

The merchants only trade for raw mats in return for chests, but they don’t accept refined mats of which I personally have a lot more of since I’ve been refining them because they take less space. I am certain there are a lot of people in the same situation.

Indeed I am, every few days I refine all my amassed mats for smaller storage.
If the player home ever gets here I can build one from Mithril ingots
All this refining and now I can’t even use them for this.
On the bright side: the recipe you can get out of them are cheap on the TP and the droprate for the kite fortunes is very low so exchanging all your mats will result in a loss of investment if you plan to buy a lot of them.
