Ya i don't see this happening sorry they would have to remake the job system over again. Allow each class more weps because it's pointless to level up a class then have to level up there weps when it's pretty much what you doing in ffxiv level up a class = the skill like Donimo said.
I just don't see the point of adding this to FFXIV it was pain in the ass in FFXI having to skill up something that took forever.
