Expanding inventory and Armoury Chest for Stormblood is a good idea, but I doubt it'll be enough. For items we use (like foods, pots, and crafting and gathering mats), the max stacks of each that aren't unique is 99 at a time, and getting more than that fills up another slot. Imo I think it's annoying and I'm not willing to buy more retainers to make more room. I think what they should also do is increase the max stacks of items we can hold at a time from 99 to a higher amount (maybe 999 or 9,999). If they're that high, we might not worry too much about inventory space for awhile imo.
