I think what irks me more about the idea of newer jobs or the inability to make them is it would be SE's own fault for falling into the trap. They bend backwards to make every job the exact same thing with different animation effects and then struggle with making the jobs unique. This would have been less of an issue if they didn't over accommodate with the fear of people not being able to play every single class ever for end game content (which they'd still be able to do but they were afraid stupid players would lock others out for their job choice).
