I get where you're coming from, and I almost feel bad saying this because it looks like you put quite a bit of effort into your post, but your argument kind of flops when you take into consideration the fact that not every single little piece of gear has a sense of individual job identity, especially when gear sets are reused and shuffled into other roles (such as the Filibuster/Royal Volunteer sets).
Take the Alexandrian Boots of Casting and the Shire Philosopher's Hose for example; two pieces I have recently incorporated into an outfit with the Hooded Fireglass Leather Vest (a role-neutral glamour piece I will add). Look at those two items on their own - what (if any) indication do they give that they are something that a caster/mage would wear? I would argue that they look "casual" enough to be worn by any role. But they can't.
As a RDM main slowly but surely shifting towards maining DNC, it's really frustrating that I can't glamour this nice new outfit I made on a class I've been playing more often, and even moreso trying to find decent substitutes that I can wear on it.
Also,
Yeah? Well what about a Monk or Samurai running around in a frilly nightgown? Edengate Striking set says hi. Without a doubt those flowing robes allow for freedom of movement.
