Perhaps they can at least filter between PVP, Raids, and dungeons and the like. I imagine Monk and Machinist got their reworks in the past due to the low player counts those jobs were known for which they would have had data on. From what I've noticed they do reworks for these two reasons:

A: The job is unpopular (Monk EW rework, Machinist ShB rework)

B: "We don't know how to design for this job from here on"/This job has some old jank: (EW Summoner, 7.0 Dragoon?)
