Something I find unlikely I would want to as well would be for the devs to break away from the existing archetypes(Tank, Healer, Caster, Phys Ranged, Melee) and do something of a whole new category in itself, back in EW I had a loose idea for a "melee caster", the idea I had at the time was specifically Judge as a playable Job, using casts to write up and produce Law cards, perhaps even being able to do walking casts as if they were absentmindedly writing on a clipboard while walking around, and then needing to get in melee range to execute them, then PCT happened and works somewhat similar to the the premise I had, except my idea of Judge would be entirely unable to attack with GCDs without a stored Law card first.
A phys Healer would be interest too, Chemist is an often-asked Job that could fit that bill, though I have even less defined thoughts of how a Chemist would be like.
