Honestly I feel that SE's plan is to leave some of these flaws in on these jobs to leave room for other jobs. (after incorporating the updates to jobs) Say you had a fencer(class) Red Mage, the fencer could sport a Temperance ability that increases melee damage for say, 30 seconds. This could help a PLD out in the long run. It's like how they began with the combo system before 1.21; everything seemed like it was missing something. I think they are leaving pieces of a puzzle unfinished slowly feeling their way around while adding the pieces that are needed.
