I’ve been thinking about this question a lot recently. I’ve spoken to a few other people and noticed what people have said on these forums across a few different threads. Some of these are a repeat of what others have said. Sadly, it’s safe to say that a new expansion or job isn’t likely.
Updated BCNMs
1) Add unique drops to new BCs, somewhat like the Flan Princess fight. Maybe not that time-gated, but certainly nothing with Shinryu’s absurd drop rates.
2) Let these unique items allow us to change up play styles. They mentioned the AMAN trove specific items were created for more niche sets, give us more unique items like that for prizes.
3) Create hardmode versions of The Wyrmking Descends (I know they just added a new Bahamut Master trial, but let’s get a new version of the original “big” Bahamut fight).
4) Create i119 version of the three mini-expansions final fights with iLevel armor and augments as chosen as rewards.
5) Update certain expansion reward items such as Tamas or Sattva Rings. Rajas is still lightyears ahead of the other rings. Most ToAU rings need to be updated.
Old Content
1) Assuming the Besieged update goes well, perhaps consider doing the same for Campaign and other old content that isn’t currently played.
Food
1) Create more unique food sales during all seasonal events (like the Green Festival already does).
2) More super unique food sales from log-in points (Like the Counter +Food)
Trusts
1) New rotation every few months (say 3-4 months). Include Cornelia, Matsui-P, and new trusts (possibly community designed).
Bonanza Weapons
1) Add these in a manner that makes them realistically possible to get. I’d love to mess around with the Hebo’s Spear or Chocobo Knife, but I can’t mentally justify it over some of the incredibly unique ones like the katana.
2) Maybe even only having one or two at a time. Could even be swapped out once a week like Adoulin rings etc. Hell, at least add them to AMAN trove (not ideal).
3) If not this, then at least Yagyu Darkblade or something with it’s effect. Add it to Nagi or something.
Weaponskill Changes
I’m a huge fan of how unique weaponskills and skillchains make this game. I understand that certain job/subjob combos are needed to access certain weaponskills. I like the idea of promoting subjob diversity, but certain quality of life changes are due:
Marksmanship, Archery, and Hand-to-Hand
1) Certain WS exclusivity from /RNG, /COR, /MNK, /PUP need to be given to other jobs. Example: SAM should naturally have some more Archery ones than Apex Arrow (and Empyreal Arrow/Namas Arrow from Ullr/Yoichi)
Staff
2) I understand the BLM, SMN, and SCH are all the nerdiest and least physically proficient of the mage jobs, but them not having certain staff WS is stupid. They’re literally the main staff jobs.
Job Adjustments (most or all of these are unlikely, but I'd like to see SOMETHING in terms of job updates)
BLM
1) Update Magic Critical Hits I to function like Magic Critical Hit II--or at least change the BLM Empyrean gloves to be Magic Critical Hit II.
SMN
1) In general, at least let BRD and COR buffs at least hit all pets. Seriously doubt they'd ever budge on this.
2) Upscale several blood pacts (see below).
3) Add in Chaos, Phoenix, Ixion/Alicorn?
4) Increase Favor potency: Garuda, Titan, Leviathan, and Fenrir.
Odin:
--Change to either different effects or a unique party buff. Perhaps remove from Astral Flow.
Fenrir:
--Remove or strongly reduce the Moon phase for Fenrir (Lunar Cry and Heavenward Howl)
--Increase potency of Ecliptic Howl/Ecliptic Grown/Lunar Cry
--Remove enemy TP generation from Heavenward Howl damage to match other en-spells.
Diabolos:
--Remove or strongly reduce the Time of Day impact on Dream Shroud.
--Increase the potency of Dream Shroud and Noctoshield.
Ifrit:
--Increase the potency of Crimson Howl.
Titan:
--Increase the potency of Earthen Ward.
Shiva:
--Increase the potency of Diamond Storm.
Leviathan:
--Increase the potency of Soothing Current.
PUP
1) In general, at least let BRD and COR buffs at least hit all pets. Seriously doubt they'd ever budge on this.
2) Change Ventriloquy to function like BST’s Snarl.
3) Give Soulsoother Head access to Curaga line of spells. Trusts have done this for years, no reason not to update this.
4) Change Inhibitors by removing the waiting to WS when the master is 900+ TP. Move WS AI changes to Speedloaders.
Update Optic Fiber I/II:
--Whatever bonus to normal attachments from OF are applied to the Puppetmaster, too.
--Example: OF I/II give a total of effectiveness of +50% with one light maneuver. With Inhibitor II and two fire maneuvers the automaton gains +40 Store TP. Having one light maneuver on would give the master +20 Store TP on top of the extra +20 to the Automaton.
--Certain attachments would need to be tweaked with how they affect the master. Truesights could give Crit Hit Damage +, etc. Turbo Chargers would be cool if they were JA haste, but I’d take magical haste, too. Barrier Module changed to Guard+. Would be cool if Armor Plates worked but they should probably just be DEF+ for the master. Auto-Repair Kit/Mana Tank would be rebalanced for master. Damage gauge changed to Cure Casting Time -. Repeater changed to DA+ for master to stack with Coilers.
--Burden + on some would increase with master’s bonus from Heat Capacitor, Ice Maker, etc.
--No effect: Attuner/Target Marker?, Reactive Shield, Tactical Processor, Scanner, Barrage Turbine, Drum Magazine, Scope, Condenser, Heatsink, Percolator (thought could probably keep this for shits and giggles), Regulator, Economizer, Disruptor
--Your SJ could be greatly expanded upon to compliment your pet. /SCH or WHM to help heal with your Auto.
NIN
1) Update Katana WS FTP or w/e to make it so Savage blade isn’t their best WS.
2) Give them access to someone with the same effect as Yagyu or add its effect to Nagi.
BLU
1) Physical Blue Magic: increase damage.
2) Magic Blue Magic: make it so you can naturally MB blue magic. Have Burst Affinity still increase the spell’s damage etc.
3) Chain Affinity: work on a charge system upon activation. Can use up to 3 at a time.
4) Unbridled Learning lowered recast or remove certain spells from it.
Subjobs:
Give a Bell/Harp to All jobs. Maybe Song/Geomancy +1~2 or something. /BRD and /GEO are in no danger of displacing either those jobs in endgame content.
