If you could add or update one feature in the game, what would it be?

[Bright-Flower]

Combat instead of what we got you would fight, dodge attacks similar to dark souls, having to manually roll, block,parry.

Also to change almost every job to their orginal ff styles. With blm gettimg all elemental spells, dragoon getting invunlable to attacks, bard and archer split into 2 jobs.

Remove acn and put sch as 2nd to conjuring
Put smn as a 2nd to thaumage.
Add theif as A a 2nd to rogue

All new jobs made to start at either level 1 or 30 (50-60-70-80 )is way to high for starting a new job.

Remove job lock from weapons.

This seems less like a feature to add and more like you want FFXIV to be a fundamentally different game from the ground up lol.

Copy wows transmog system in addition to ff14's dying
Collect a piece, added to your collection and can apply it without space limitations

For a new suggestion on my end though that I think nobody's mentioned yet, a sort of dungeon/raid/duty log where you can easily in game look up what drops from different duties and bosses. Largely for an in game resource for glam hunting.
