To get this straight...

They've taken skills that were previously on some jobs as level unlocks; some of which were cross-class skills, and made them separate as this so-called cross-role skills; all while doing away with cross-class as it is - or if so, was?

If that's right then yes, personally I consider that a nerf... big time... as well as being pointless as they took a system that exists and added a few good additions to it - yet made it worse; one step forward - two steps back etc.
