The crafted (not the reward gear) PvP gear should be convertible.

[Alhanelem]

Everything else in the game that's crafted is convertable, so why not these? Technically speaking they don't HAVE to be used for PvP (and in fact the accessories are a step above the only other functional rings that don't use rose gold even out of PvP). Moreover, why do we have to spend a whole reward item's worth of wolf marks to buy resistance materia? Why can't this stuff convert into it (and if not that stuff, normal materia)?

Would it really break the game for gear that you can craft, buy, and use anywhere to be convertible? Come on.

Edit: and in case anyone doesn't realize this, it also creates a problem where this gear doesn't get consumed and will thus become worthless even though it has its uses, since you can't sell it or convert it. You can only NPC them for like 100 gil.
