More armoury space isn't just a "wish," it's an absolute necessity.
There will be class specific armor for all of the classes:
13 adventuring classes
8 crafting classes
3 Gathering classes
That's 24 classes. This leaves only one extra slot in the armoury for weapons, which is VERY counterproductive thanks to raid drops and the like. Plus if they ever want to add more classes, they'd be out of space.
