Please lift glamour restrictions!

But please answer me this nobody has answered how does what Im suggesting effect you in a dungeon , raid, or whatever kinda content you like to run on the game. Other than your oppositon there is really no reason at all to why it that would drastically change the way you proceed in combat. This idea doesnt effect anything other than people dont like the idea of it.

It does. The art-team designs those gear thats for one specific class for this one specific class and thats influencing how they're designing it in order to represent that one class best. If you lift the restriction on it thats obviously gone and we will see a lot more of generic armour because after all everyone can wear everything on any job. Look how generic and recycled the shared pieces look already!
Let the art-team design those special gear for one specific job to give them the chance to make it fit that one job really well because its only meant for that one job.

And please... stop using "but we can do silly stuff with [bikini/pig suit/maid costume/event gear/etc.] already!" as an excuse - that stuff is meant to be funny and silly while the real gear isnt (...except for the last SMN-set, maybe). That gear was designd with the idea of it being funny in mind, while artifact gear (or other restricted gear for that matter) was designed with something else in mind.
As flattering as it might be for the design-team that you like certain parts so much you just want to wear them with every class (and yes please, we could use a few more nice shoes/high boots for all classes) I also feel its a bit... disrespectful towards the dev-team to tell them "Because you put this one funny thing in, I demand you to give me everything now!" and not respect that they might have other plans in mind (as in: keeping an eye on job-identity and not letting tanks wear robs or have mages run around in heavy armour)
