Can we please have airship exploration mats added to diadem for spoil trade ins? Not all the mats of course, but maybe something like when the mats become a patch or 2 old they get added to Diadem's spoil trade in. Been having horrible luck with a lot of these rarer mats even with several airships as maxed as they can be... It also keeps these mats to the airship/exploration thing, it'll help those that don't actually have airships, and may even help Diadem stay a bit more relevant.
