Why can't the DoH/L gear be made usable for DoW/M for glamour purpose?

[Felis]

Just seems somewhat wastefull to restrict them.

And the argument that it isn't made for fighting isn't that good considering the emperors new wardrobe and certain other gear such as snow man hat and gloves.

Heck the gear would even be more valuable to craft seeing how DoM/DoW can't get them otherwise.

To change it, the gear have to be "all classes". And then there is no reason to craft more than 1 DoL and 1 DoH set instead for every class an own set. Not only would WAR running around in LTW set, but also WVR in ALC set, or MIN in FSH set. It will be like every DoM class running aound in SMN AF2 set.
