We really should be able to glamour other jobs' sets

[technole]

If i recall the last time it was asked it was dismissed under that it would be ridiculous to see a job use another jobs weapon...

Yep, YoshiP denied the suggestion several times since ARR. He doesn't like the idea of a black mage wearing tank armor. Or a Monk wearing Dragoon maiming gear, that'd look too weird. People should let it go.

There is a reason melee don't share a set between all of them compared to tanks and healers, aside from loot reasons.
