Sadly people will always take the shortest easiest way. Just like everything in nature, this is built in to us and very few choose a more diffucult road when given the choice.

After a fair bit of reading, I don't think there's anyone that can say a "good" job was done when forming the classes:
Cnj gets a mix of nukes(that should be thm's) and heals but little by way of support spells and nothing white magic DD(except holy)
Thm gets busted elemental spells and only 1/2 the wheel, setting cnj spells leaves you w/ a couple gimped ones but still no water
Pld the job that makes the most sense to be tanks, as throughout history both real and fantastic and FF has been the uber defense tank that defined the word tank, yet pales in comparison to war, and come on WHM and BLM tnaking shit?
War overpowered but people ignore it's overpoweredness because it gets 3 jobs done at once
Arc becomes brd, arc was headed toward DD and ends up the prime support job???
lnc/drg ongoing adjustments break one thing while fixing another, at least now I land 70% of my attacks vs. launch where 10% was doing GREAT
Mnk probably the closest to balanced and solid, it's dmg outshines other melees but not so much that it's absurd, it takes hits well enough but not better than a tank, it mostly makes sense.

End of the day, full on class/job reforms with a little clear direction instead of patchwork jobs that just further break already broken patchwork classes.

Yeah thm needs the full wheel, cnj needs proper white magics and not elemental nukes. Lotsa jobs need lotsa stuff.
