Bard's in a weird spot because fight design matters so much re: BRD vs. MCH. If there are a fair amount of long-lived adds (most of Gordias), Bard can really shine, but when you have a high-mobility fight (most of Midas) MCH pulls ahead quickly as we've seen. Part of that is the turret, part is of course their movement procs, and on the other side there's the difficulty of keeping Jaws up during certain jumpropes as well as (and this gets overlooked a lot) the near-uselessness of Flaming Arrow in cases where the boss needs to be moved around a bunch.

So any buff would presumably be aimed at mobility (without making multi-DoT better) and possibly making Flaming Arrow less terrible in those spots, or perhaps something for Foe to either fix or make up for its general clunkiness (maybe they just wave the white flag and make all songs instant cast). I could see returning Straight Shot to 70 TP and just making it always instant, kind of like a pseudo-Ruin2 situation that's not as terrible as Feint.
