For the most part... QoL buffs.

Such as The Wanderer's Minuet button becoming Pitch Perfect while active.

Maybe merge Raging Strikes into songs? (Would increase the uptime... So would have to be balanced around that)

Reworking how Foe's Requiem functions (Cast time and MP drain) potentially working it into Battle Voice.

Refulgent Arrow replacing Heavy Shot while under Straighter Shot.

You know, mostly just cleaning up button bloat. Allowing for more freedom to add new skills as well as making it less annoying to try and organize action bars as a whole.

Outside that kind of thing, I'd be looking at stuff such as:

* Repelling Shot being altered slightly. So that when cast outside of the 5 yalm range it's currently restricted to, that it reduces enmity by 50% instead of jumping backwards (While when cast within 5 yalms it's the same jump back)

* Army's Paeon being reworked. So that it provides a more useful effect. SkS is of limited use for BRD... (Also, it has a hard cap on useful procs... Once you have the full stacks, additional procs do nothing. Meanwhile, MB and TWM allow you to keep using new procs for their entire duration)

Maybe reworks or boosts to Nature's Minne/Warden's Paean respectively to make them more interesting skills to use?

Other than that, I don't really know. BRD is currently in a pretty good place. Both the fantasy of both Archer and Bard are pretty well represented and mechanically, they have their place in the game as a supportive DPS, with DPS rotations that make sense. Really just a bit bloated on buttons with a few skills that are a bit "Ehh..." on the whole.
