As said before, ACN is superior for giving this DPS a more supporting role. Heal, in-battle-non-trait-dependent raise, and lower incoming damage to entire group via 2 methods (EfaE/virus) which can be rotated with the healers for a lot of uptime.
Bard's role is DPS but they are support focused DPS which people are getting hung up/confused on. They queue as DPS, they attack monsters but their charm and primary use comes in the form of their supporting songs which makes them indeed support. The only issue here is in XIV all support roles come in the form of augmented DPS roles.
