My first suggestion is for the ability to buy extra retainers in game, for say 100k-200k each? With a max of 3-4 at the very least. As it is, both my retainers are maxed and I have my own FC for just myself with a maxed three section bank.... so I do think the need for space is there.

A second suggestion is for the armory chest to be expanded as well, because if you are leveling a tank, DPS, caster, crafters and gatherers, then you don't have near enough room in your chest for all that gear unless you level them all at equal rates which is unreasonable, so expanding it to say 35-40 slots would be a good idea.

A third suggestion is for a fashion bag, so all those event clothes, weapons, hats, etc can be stored that can't be in the wardrobe in the inns.

Its really my only complaint in game and I really hope this gets taken care of at some point.
