The simplest solution to the glamour issue

[FaileExperiment]

The glamour system is pretty poor in this game. Ideally, glamour should actually work similarly to gear set feature. Creating and editing your glamour sets pulls from a catalog of all the items you've ever had bound to you, not your inventory. You could then equip this glamour set just as you do a gear set. That way, your glamour would apply to any armor you have on even when you switch it, because it's actually applying to the slot, not the gear itself. Creating and modifying glamour sets would also not require any kind of consumable nor have level restrictions, only the typical class/job restrictions. You would even have the option of tying a glamour set to a gear set, so they switch together automatically.

If for some reason you did want to include some kind of consumable use, I would make it where you need to use a consumable to add the gear to the glamour catalog, but not for making/editing glamour sets. I think consumables are lame to begin with, but there are strangely those who live and die by them.

This system solves most of the current issues people have, like inventory space, general ease of use, and glamours that force you to apply them to different jobs other than the ones you actually want. It's already there too, in the form of gear sets, so aside from the glamour catalog, SE has all the pieces they need already.
