Two possible things for Bards, although both together would be overkill.

- Instead of Raging Strikes being a straight up 10% attack buff, make it boost critical hit and direct hit rate by 5%. Makes up for Bards being unable to benefit from their own party crit buff/Battle Voice.

- Overhaul Army's Paeon. Instead of lowering weaponskill/spell recast timers, make the stacking effect boost crit rate by 1.5% per stack (up to +6% at full stacks) and boost Straighter Shot activation rate by +2.5% per stack (up to +10% at full stacks), a significant increase in Refulgent procs during this song. Considering most Bards open with Minuet opener -> Ballad -> Paeon -> repeat, this means that Bards are able to use Paeon to set up their next Minuet burst window with a powered up Iron Jaws before switching, and a higher chance of having a Refulgent Arrow proc ready as well.
