While I would love a lot of these ideas and know they would go a long way to improving the glamour system, we won't get anything like this in FFXIV.

Restrictions are partially to blame as they add another dimension to work around if they wanted a catch all glamour dresser. However, this is a small constriction. The bigger one is all the data contained within a single piece of gear, which included its stats, spirit bond level, materia slots, base color, etc.

One thing they can do is make any glamour gear like cash shop items, and like items that have few stats able to be placed in the armoire. From there they can figure out a way to nuke the stats on gear they won't mind eliminating the restrictions on. This would benefit a couple days. One would be they wouldn't have to release copies of previous gear that have the restrictions removed. The other is it would relieve a ton of storage space for players and open up their glamour options. While we can't look at every piece of gear in the game at one location. We could at least be able to look at any piece of gear we've touched.
