While i can see how players being mainly crafters might need a lot of space, you are kinda too negative here. It is not like you have only 30 inventory places to start with and have to put 15 euros in the cash shop to unlock 10 more, while being limited to stack a maximum of 10 items. I am not saying that there isn't some issues, but FF14's inventory is by far the best i have seen in all the mmos i have tried, even wow's one can't compare to it. You couldn't believe how you will get way less space for a way more expensive price on some so-called "free to play" games. I still remember being impressed by how many free places i did got when unlocking my first two retainers.

Are you sure you dont keep too much useless things ? Not being that much into crafting two retainers are plenty enough for me, even by keeping outdated currencies (like these coeurlregina's horns, it is not like they will add new items for them...). Today taking two minutes to look at my retainer's inventorys i was like "why do i keep these mogs palace of the dead skins ? Oh i remember, the price was too low when i dropped them, maybe it is a good time to do it now with people being all in eureka, prices sure must have gone up", and here you go, i dont have to worry about free space for a while.
