This would be a much better system. I understand that the armoire should work more or less like this and they've said that they're struggling to fit more into it (a silly notion since they should have planned to include all seasonal equipment that they planned to release at the very least), but this would, in practice at least, solve the inventory problems of a lot of players without increasing inventory space or adding additional retainers. Personally I have about 100 glamour items on the retainer I've designated for armor/ weapons and that's after reluctantly trading in about 30 items for seals recently (and never bothering with several things I didn't think I'd use).
