I was rank 8 before the patch, still rank 8 after, and I have every (obtainable) title in the game except for the following:
Maze Overlord (1000 MMM mazes, at like 500+/1000)
Legendary Blacksmith (escutcheon, on spirit stage)
Paradise Regained (master trial)
Founder's Pride (master trial)
Master of All (master trial)
I also think Ballistager broke for me and didn't award when it should have for some reason, I'll have to recheck that. I'm not including the 3x Besieged BCNM ones either as those are functionally impossible on Bahamut (maybe at 150+ we'll start losing it again).
I also have every ROE in the game done and have completed roughly 98-99% of the content in the game, though I do have some notable gaps I'm tracking to work on eventually that don't reward titles:
Odyssey V25 atonement 3 and 4 clears
Final Domain Invasion dragon vorseals (at like 280/360 of each)
Missing ~8 Bastok Campaign Ops
Missing ~30 Windurst Campaign Ops
Pretty much all of Monstrosity (only have one species at lv90)
Other things that might have an effect would be total master levels (most of my jobs are 0-30, some near 40, no 50s), total amount of reforged armor (have barely touched limbus, most empy at +2, didn't touch many jobs pieces), total amount of completed REMAP weapons (zero relics, two mythics, two empys, all 16 aeonics, two primes here), etc.
My immediate goals will be to try and finish the crafting shield as that's likely worth more than average and then to buckle down on Monstrosity as others have said that seems to contribute quite a bit. Work on the high end content when I can find a group, and work on the gear/low content in my downtime.
