Extend Classes into full Jobs?

[Bishop81]

Making Classes viable is just an annoying balancing issue, and frankly, the worst idea ever... Everyone wants unique jobs, so why would you want people to play bland classes with abilities from all different classes?

Here is the part that many don't seem to get. If they do extend Classes into full Jobs, what makes you think they won't add abilities to the Classes-now-Jobs and make it unique?

You will be surprised how much a difference Job specific abilities can make to rotations and general play style.
