Before I get started, i would like to state that i know how tricky this would be to put in, and that i just really wanted to throw this idea out there.

With classes/jobs we get locked in to 1 or 2 weapon types, which is due to the unique armory system we've got. What i suggest today is the ability to glamour weapons from other jobs/classes (Relics excluded) onto a class/job that usually doesn't have the ability to use it.

For example, a BLM wielding a staff that is glamoured to look like a book.

For DoM classes, this is relatively easy, since their weapons are not what they use to attack. However, when we get to DoW classes, it gets more difficult, because DoW classes directly use their weapons to fight.

So i've made this chart, displaying what could possibly be mixed/matched between them (this includes heavensward jobs)

Archer<->Machinist
Marauder<-> Dark Knight
Dragoon->Paladin (a spear and board tank)
Dragoon (possibly)<->Marauder
Ninja<->Paladin (If you can get behind the idea of paladins having a dagger, or a ninja having a sword)
Monk<-ninja (monks could still punch people, but while holding daggers or something)

And that's all i could think of for DoW at the moment.

Again, DoM are completely interchangeable without much difficulty.

And, just incase anyone forgot, Glamouring is the act of projecting the shape and appearance of one object onto another, while still actually wielding the original item.

I do wish to flesh out this idea some other time, but i just really wanted to throw it out there. Tell me what y'all think about it.
