I'd like to see the following:

Exploratory Content: Although Bozja and Eureka may not be everybody's particular cup of tea they both served to bring players together in a way that hasn't been seen in Endwalker. I'd like to see exploratory content become a staple of every expansion and be refined with each new iteration to have a smoother and more satisfying gameplay loop as well as more rewards to acquire. Including items that are rare and will sell for quite a bit of gil in order to facilitate longevity.

Player Housing: Although I am lucky enough to own a large house within the game, many of my friends are not so lucky. The Elder Scrolls Online allows for players to take a break for months or even years without the risk of losing their acquired houses or furniture. I'd like to see a similar safeguard implemented within FFXIV since 45 days - a month and a half - isn't really that lengthy a period of time. At the very least, I think it should be rounded up to two months.

Character Customisation:

Let's not beat around the bush - there's some very dubious and outdated design decisions plaguing this game. Perhaps one of the most prominent examples is the lack of authentic eyebrows for Highlander men. The face paint simply doesn't cut it, particularly when many players have spoken up over the years asking for more of a bone to be thrown to those of us who like and/or play men in this game. Better faces along the lines of Snow (FFXIII), Gladio (FFXV) and Basch/Gabranth (FFXII) would go a long way towards encouraging more people to try out this game and pick out a player avatar that appeals to them.

In addition, the game should take cues from World of Warcraft and The Elder Scrolls Online by taking the time to add new scars, tattoos and facial hair as customisation options. More short hairstyles that are primarily designed with men in mind would be excellent as well.

Deeper Dialogue Choices:

The game is in a rather strange place these days where it is becoming more akin to a single player game on many fronts. That would ordinarily serve as an excellent opportunity to grant the player more agency in regards to certain situations. For example, not everyone is eager to have their character fawned over to such a large degree by G'raha and Alisae. The option to put one's foot down would be wonderful. It would also be great to have more choice in terms of how our character chooses to react to some of the deeper revelations in the MSQ's. Not everyone is interested in the 'chaos gremlin' archetype that the game desperately seeks to push upon our character.

Reconstruction Content:

I'd like to see more of it, once again as a staple moving forward. There are a lot of places within the game world - such as Garlemald and Ala Mhigo - that could stand to be rebuilt. Having each server come together in order to rebuild parts of the game world is peak MMO as far as I'm concerned.

New Rewards:

From time to time and in order to encourage older content to become relevant again to both new and veteran players alike I think it would be wonderful if new minions, mounts, cards, emotes, glamour, orchestrion rolls and furniture were sprinkled across various aspects of the game.
