It seems the devs don't actually know what we want. Here is
Blade & Soul, a free two play MMO. Their Wardrobe system works by listing every possible "armour" and allowing you to move any outfits you acquired into it. You can pull them out at any time, provided you're subscribed. I fail to see how a triple A game like FFXIV cannot basically copy this system. The server excuse is just annoying at this point. Weren't they relocated to upgrade them? All this comes across as is Square Enix knowing retain subscriptions would decline.
That isn't the argument though. At least it isn't mine. I adore both the Paladin and Dark Knight AF outfits yet I'm unable to wear both if I want to maintain a progressive ilvl. If I choose Paladin, both Warrior and Dark Knight default to whatever the raid gear is. So instead of enjoying all the unique job glamours, I usually end up shelving them fairly quickly.
