I feel that an issue with the game that has risen to the upper end of the pile (for me at least) is that there isn't a job/class in the game that has a large AoE attack move (and relatively spammable). It's not about balancing any particular job among those in the game so far, it's about completeness. There seems to be this unwritten golden rule that the player must suffer a reality of being aggressed by even level 1 enemies after slaying a bunch that were nearby. I just think it's a little annoying and there's no way to prevent it. Kind of undermines the might of your character to be challenged by a level 1 ladybug that was out of your initial attack range, after brutally destroying all the other mobs that were closer.
All I would like to see is just ONE of the classes in the game get given a 25 yard AoE attack skill with a good amount of potency, and have it run off a 3-charges system like Machinist's Gauss Round and Ricochet. I just think it would 'complete' the game's attack profile more to let players have a skill where, at level 80+ with respectable gear, they can travel through an ARR area and use the skill to wipe out ALL the nearby mobs in one hit without a chance of being aggro'd afterwards. It's a bit unfair that plenty of enemies have huge full circle AoEs themselves but we can't have one? It's just about having a bit of fun and wouldn't break the game at all, maybe even add an effect/condition that stops the player from getting drops when using the skill, to avoid it being used to farm gil. Given that ninja's Mug skill *increases* drop chance, this should be easy to implement. With level 520 gear, I would expect we could wipe enemies up to level 20 with such a skill, maybe level 25 with endwalker's endgame gear in future. Then there's the incoming stat squash to consider- but even after the stat squash it'd be nice to wipe level 25 and below mobs with said endwalker's endgame gear. Attach it to the cooldown(s) of one of the job's other skills as a balance if need be. Naturally I'd like to just spam it repeatedly but a 3-charge system is what we're more likely to see.
