Does the class restriction of Glamours need?
To cast Glamours, the base item and projected item can be equipped by the same class or job. I think we could enjoy Glamours more without the restriction.
For example, I often play healer with male character. But the most of healer's gears are kind of girly, or white, so I would like to change the arms and legs into Ranger's ones to make good look. And some people want to cosplay NPC, but it is hard with the restriction.
In addition, as some may notice, in 4.0 the gatherer's and crafter's gears have the class restriction so fighter and caster cannot put on these gears, though the gears before 3.X has no restriction. So we unfortunately cannot use them as Glamours.
It is true some gears like Artifact Armors is strongly connected with its job so I think there gears should remain unique. But except them, there is no problems if the almost all gears should be available for Glamours beyond the class.
