A lot of players bring up this argument, but I don't really get the logic. The best (though exaggerated) comparison I can think of would be if someone refused to use a landline telephone prior to the invention of the mobile phone, because you have to be in a particular place to use it.
It does a specific useful thing that you can be getting value from right now, even if it doesn't do everything it could do.
If you set up plates for glamours you use at all frequently, you permanently have them on hand (as long as you're in a city zone) any time you want to add that appearance to your gear - all in one shot, without spending prisms, and you don't need to carry the glamour items (if inventory space is your concern).
Mostly likely you'd thrown out one of the rings saved to that gearset, so it only tried to retrieve one ring from the armoury chest while putting two in from the previous set.
