It's interesting what passes for a "mini rework" in the relatively static context of FFXIV. I would call Astro losing their old cards a mini rework comparing other MMORPGs, and the only actual rework the game ever had was Summoner. As in, the class was essentialy hollowed out and some of the textual bits and visual f/x stitched together into something new.
But that only highlights how much too little they are willing to work on job designs, IMO. Stuff like this should be happening every .x-patch. Other games do that, they rip out entire mechanisms repeatedly, partiually because it's extremely difficult to design stuff in a vacuum. It's easier to change it, then change it back or do a third option when it doesn't work out!
