It still requires carrying around large amount of equipment.

Even in FFXI when I played a single job dedictated, I hated carrying more equipment then I needed. I hated Gear Swapping. I'm a minimalist I'd rather have just what I need on me. Even if you seperated the equipment inventory from your normal items inventory it would still piss me off having so much equipment to carry around. I'd rather have the freedom to pick what I want and wear it.

With how I described the system lets say you get a Body Armor from an NM that you really like but its not part of a set. You can go and find and mix and match pieces of crafted gear to get a matching oufit set together for that Body Piece. Thats what I love about FFXIV. I don't like looking tacky, I'm very fashion oriented when it comes to how my characters look which is one of the reasons I hated WoW so much. The boots in that game make me want to vomit.
