I would be more for this not as a retainer but being able to level my crafting classes... It could be an app purchasable on mogstation with a one time fee, and perhaps it would let you craft using all of your own and your retainers inventories only. I would pay for more retainers if we could have this as an interface for crafting and accessing them all... I'd stock up on all mats I might need. If we can desynth as well... This would be awesome...
