I think people's complaints about the glamour toilet are based entirely from what they wanted this system to be, and not what it actually is.

People wanted a way to have different glamour for every combat and crafting job and this doesn't give you enough plates to do that. Maybe it will someday, but right now that's not what this system does. However, it does let you cast the same glamours over and over freely, which allows you to change your glamour more often and possibly keep your glamour intact when you upgrade your gear. Also, you can glamour the entire contents of your armoire with no prisms required or anything having to be flushed into the toilet forever, so if you want to dress up in seasonal event gear for various events you can easily throw some on a plate and freely glamour it on.

It does need work, there's no good reason we can't change glamour everywhere we can change gear sets. And the 200 item limit is going to be too low, that or the inability to remove things needs to change.
