The funny thing about inventory space is that no matter how much of it you have, people will always want more. FFXIV is incredibly generous with inventory space compared to many games that I've played. In FFXI, you didn't have an armory chest. All of your gear, for all of your jobs, was in your gobbie bag or not at all. That bag could be upgraded to a maximum of 80 spaces! Now we not only have a 100 space inventory, but an armory chest with 25 slots per item! The amount of inventory space we have is insanely generous already.

That's not to say I don't have inventory troubles. I'm a crafter. My inventory is almost always packed full of materials, finished works or catalysts for repairs and melds. I'm constantly battling against the struggle. But I realise that it's not the fault of the system, it's a fault of how I play the game. And I know better than anyone that if I had a bigger inventory, I'd just find new ways to fill it back up.
