Let's hope it is as easy as SE is making it sounds. Because if I recall correctly they mentioned you'd have to use macros for this new feature. Which leads me to think that every time you change from SCH to WHM or vice versa, you'll have to keep reaplying the glamours on the tab. Hence why gearset macros.

Sadly the number of available slots is also a problem if you really want all your jobs to look different. You need 13 slots if you want all your combat classes to look different, and that number is increased to 24 if you also want your gathering and crafting classes to look different as well.

I also recall Yoshi saying that items that can be put in the armoire wouldn't be needed to be converted into glamours.
