The release of abyssea did and does encourage the leveling of more jobs for each player. And SE wont complain much about that. Its keeping ppl playing/paying.

So with that encouraged, obviously new (not rly new..) problems will arise that need to be addressed. In this case inventory. (Hence, not rly new) For those lvling multiple jobs, or all 20 jobs, inveotry will now be a bigger deal then ever.

This about this; if you had 20 jobs leveled, and you had each one geared with only a single set, no extras, no gear swaps, no tp gear, resting gear, ws gear, nothing.. you would still be left with 16 equip slots *20 jobs = 320 peices of equip. (or 300 if you count 15 slots)

That drasticly high of a number requires attention. Which is reasons why ppl will look to reuse peices of equip on multiple jobs. And why the dev team has introduced things like the Porter moogle (Thank you for that one!!).

While the origional idea on ffxi when it started was to keep inventory small and encourage player managment, things have since then evolved. And with the now encouragement of lvling multiple, if not all, jobs, the two ideas do not mix. (And obviously the first one was dissmissed long ago)

And all that is jsut for equipment, much less other items like crafting. It adds up to a lot of space. (And on a perosnal note, for ppl like me that enjoy decorateing their MH for their Moogle, space is even more of an issue. Currently my mog safe 65/80 furnishings alone!)

So more space is always needed! You could expand it to 1000 inventory spaces and some ppl will still want more lol. (Except then youd have ppl complaining they cant find certin things because they have to search through too many things and end up asking for an item search function or something.) There will always be something!
