The class <> job system in my opinion adds flavor to the game, it gives it that little bit extra like cherry on the cake. It would be simple to have your cookie cutter job with pre set skills, abilities, and so on. Like in XI were 5 people would play 1 job the exact same way, as you could add no variation.. With the 2 class make 1 job deal you still have the per job skills, but past that each person can add there own little touch to the job, determined by how they play..
That aside, the jobs and classes can be played quite differently.. and offer different things to the table.. in some fights a class can easily out perform it's job, and the same is true on the revers side of the coin... I am now sure why OP would want to remove this aspect.... even if you are not happy with it you can over look it and focus on something else.
One does not make a better game, by changing things for no solid reason.
