If Square-Enix directly asked you for suggestions...

Oh there are so so many things. Here's the short list.

Retainers:
Need visor toggle
Need name toggle (not player name, the retainer name)

Items:
ALL QUEST REWARDS SHOULD BE ARMOIRE COMPATIBLE
ALL GS REWARDS SHOULD BE ARMOIRE COMPATIBLE

Housing:
Stages need to be treated as flooring so we can place items on them (without floating)
Fake windows useable on partitions
Hingan Pillars
Indoor Fountains
Indoor Mailbox
GARLEAN THEMED HOUSING/FURN
Toggle for housing district music
Orchestrion music to extend outdoors (or outdoor orchestrion--why the hell have the ambient sounds otherwise?!)
1st/2nd/3rd floor lighting to be separate toggles
Seasonal/Weather settings for personal yard

Glamour:
Too many to name. But I'm tired of needed multiple gear sets for the same role just so I can have individual glams. Roll with that.

Gameplay:
This might be silly, but no more job restrictions when que'ing for instanced battles. Like if you que as BLM but decide you want to be BRD. As long as the role is the same, why would it matter if you changed jobs? Having to un-que and re-que is just silly.

Crafing/Gathering:
This is just a bag of cats. Really. However I am pleased with the SB skill additions but still have no idea what Whistle does. Guess that new gear will have to wait.

Anyway. Just a few things. o/

No more jumping games.

Allow flying in cities.

Some objective, some subjective. Mostly the usual...

Catbutts
Glamour log
Guaranteed drops in all dungeons, not just leveling
Drop of choice after x runs menu driven system, like ex primals minus tokens cluttering
Jobs not having their entire identities ripped out each expansion
Changing the devs' current good idea/horrible implementation into good idea/great implementation

• Make boss rotation speed adjust automatically in real time to the average DPS taken, updated each second, essentially making it impossible to skip mechanics with high DPS (this would actually cause too much DPS to make the fight HARDER, with mechanics coming sooner and more frequently).
  
• Revert the change to Cleric Stance and healer classes damage (change it back to scaling from INT), still making cleric stance a role skill. But make it work like nocturnal/diurnal sects, meaning you can only change stances outside of battle.
  
• Enhance the damage penalty on tank stances (Shield Oath, Defiance, Grit) to 70% from 20%, enhancing aggro generation accordingly. Also introduce a 30% damage taken penalty on DPS stances (Deliverance / Sword Oath / Darkside). Make it so Survival CDs can't be used while on damage stances.
  
• Nerf how VIT scale HP by about 10~15% of the current factor, effectively lowering everyone's Max HP across all levels. Also buff damage scaling at the root calculation for all enemies in the entire game by about 10%.

Those would be things I'd LOVE to see changed in the game right now.

I want to hope that points 2 and 3 are trolling.

The first will also just be to revert mobs to 1.x TP-based (generated from damage taken and dealt, rather than as Stamina 2.0) rotations. Personally, I like that we can skip phases, not because it can reduce fight complexity, but because it gives a greater sense of agency and progressive impact. That said, certain adjustments would be great to see. I hate that jump phases get to be a ridiculous portion of overgeared fights, rather than their scaling in turn.

Kinda rant kinda truth, I'd suggest make more useful the Hall of the Novice until lvl 70, not just teaching the basics (like dodging aoes, getting all the aggro, etc.) so people can get good at what they are doing. A more difficult training that makes the player use and understand what all their skills does and to move faster with their gamepad or keyboard/mouse. Maybe using the content for training, instead of wiping by failing a mechanic, getting an X (similar as in 2nd boss of Bardam's Mettle) when they fail. I'm sick of having such horrible parties and it's making me lose the will to play.

Actually all 3 points were related. The root of my proposition was the utter and complete destruction of the so-called "DPS META". By making extra DPS irrelevant, and at the same time invalidating healer/tank DPS completely, the raiding community would go back to valuing the roles for what they are, effectively cutting off the root of almost all toxic behavior in the game, and promoting better interaction between players of different roles.

...and at the same time invalidating healer/tank DPS completely.

I'd be so bored if I couldn't turn to Sword Oath and do some DPS or if I couldn't use Broil with my SCH and just carrying people's hp. Your suggestion is nuts

I get the feeling reality is well divorced from your concept of "roles" then, whether in the current game climate or otherwise. If the root of your idea is to invalidate the exchange of outputs available to a player, whatever their role, I also highly doubt the result would be one of "better interaction".

My only suggestion would be to slow down on content creation and more on fixing the code. I mean come on, FFXIV is the only modern AAA MMORPG that can't do things due to *insert server excuse here*. I get that this would take time but adding to the issue(adding more gear etc every major patch) while slowly fixing it /shrug

[Anienai]

Just thought of another cool idea. What if the in game music title/composer appeared? It can be adjusted in the HUD section.
