So glamour plates are dumber than anticipated...

and this needs to change if squeenix wants to keep up with their biggest competitors such as Guild Wars 2 and World Of Warcraft (both these games have no class restrictions for glamour)

This is incorrect. On Guild Wars 2 you unlock the visuals (aka skins) of the equipments you discover along the way, but if you use Heavy armor, you can only glamour heavy armor skins on it.
And the same goes for World of Warcraft. You can't use the transmog system to make your Mail gear look like a Leather piece. So yes, both of those games do have "class" restrictions for glamour. You're just forgeting the fact Guild Wars 2 and Warcraft don't alow you to play one single character with all the classes unlocked for it.

That being said, as far as glamour goes, GW2 requires you to use Transmutation Charges, that are far from cheap (only being obtainable through heavy farming or cash shop only), and THAT is the actual glamour. What are you referring to is the Cash Shop skins that just override gear that you're using, but you have a set amount of skins available, and their pieces are not interchangeable. So in regards to those, everyone looks the same with different colors.

On the Warcraft side, you have interchangeable pieces of gear you can glamour, sure. But no dye system. And as said above, you ARE restricted by the type of gear you are using. You might be a Shaman and have access to Cloth, Leather and Mail, but you can only glamour the pieces that you are using with their respective type of armor design.

I know this Glamour dresser isn't perfect, but let's stop pretending that any other game ever created have better glamour implemention, because they all have flaws in their own way. Final Fantasy's is just a first step, and I am sure there's a lot that is going to improve.
