I hope for a complete 180 to this constant simplifying and homogenisation going off in the jobs. While primarily my biggest gameplay gripe with this game, the lore behind our actions was a highlight for me.
Return of job and crafter quests. While shb it was fine, but the role quests I'm really not seeing the supposed improved quality having done 4/5 of them now. Likewise in the studium, while some of them were good and funny, others didn't seem anything related to well...the crafters i use for them.

I'd like the relic to start asap, and for future expansions, same time as savage. Back in ARR's start Titan hard's weapons and the relic were the highest levels you could get until they added glamour weapons and fixed turn 5 of the coil.

Like everyone here, I'd like more deaths rather than fakeouts story wise.
If we got to have time travel, lets have it done right and sensibly, and not with major plotholes please. Done right its excellent. Done wrong and it kicks away any impact.
A more grounded story seems likely which is good.
More downtime scenes with our companions like ardbert in the first and the takeout we had in the annex. They were a nice change of pace

Finally...please dont kill off the well written villains so much and leave the shit ones alive. Could have avoided this plots are really tiresome. Zenos, yotsuyu and fandango were all really frustrating. If the villain's doing something dangerous but they are open, let us smack them damn it like at the end of In from the cold shoulder tackling the baddy.
