With the amount of good looking gear, other kind of items (crafting, consumables, etc.) and three new jobs introduced with the expansion, will we ever see an increase to our armory space and/or our retainers without having to pay even more than our monthly sub?

It's kinda sad to have to discard those items, that you would use either while levelling to 60 or for glamours, not to mention that it makes kinda difficult to save gearsets for glamouring and to re-use with compatible jobs. The later was easier during 2.0 thanks to shared gear (DoW and DoM specific), but now most of the good gear (green) is restricted to a couple of jobs, thus making our inventories full and us unable to save these gearsets in advance.
