Currently, we're looking into implementing a satchel that will not be added for all characters, but rather characters that have progressed to a certain portion of the game.
I'm more than cool with this. Characters made just to store stuff generally don't need more satchel space because they're always near a moogle, and characters made just to be a mediocre White Mage/Summoner/Thief/etc. generally don't have that much equipment in the first place. If there has to be a compromise, this sounds like the best possible option.

However, what I feel needs to be done is to start using the storage slip system within mog houses.
