Rework healers to make them interesting and engaging to play, either through making healers green DPS or making healing itself engaging. The horse has been beaten to death as to why, I don’t need to repeat what I and literally H U N D R E D S of players have said on this forum.

Add a daily roulette for Rival Wings so it’s more accessible

Make 4 man extreme versions of old dungeons, and make future dungeons more varried and interesting (more optional loot and enemies for leveling)

Take the current crafting system and throw it in the goddamn dumpster and light it on fire, and come up with something more engaging. How? I honestly have no clue! I’d have to brainstorm for literal weeks on how to fix the boring dumpster fire of 5.2 (think it was 5.2) and beyond crafting.

Add in armour shades, like metallic and non metallic, or some other way that non ARR dyed armour pieces don’t come out looking metallic, in comparison to the clean ARR versions, while still keeping the option for a metallic hue.

Revamp the TOS so swearing (unless it’s directed at a player to be rude) isn’t a banable offense, use the swear filter if you dislike it.

Add in level 1 9S gear and maybe, juuuuust maybe, add a Flight Unit mount, you know, things that should’ve been in the raid in the first place???????

That’s just the things I could think off the top of my head, but my god, I could probably come up with literal DOZENS of things I’d change with FF14.
