I would have loved to see more support utility with Bard songs. Right now we get Foe Requiem, Army's Paeon and Mage's Ballad. Well, and Swiftsong... but no one counts Swiftsong. They're great skills, but very niche. Most good mages can manage their MP fine, bard or not since there's no guarantee you'll have a bard in your party anyway. TP can be beneficial, but it regenerates fairly fast so again, not too often used. Foe Requiem is awesome if you have a mage in your team, and is easily the best one we have as it has no drawbacks to casting it.

I'd like to see some damage buffs for melee, evasion buffs or maybe even a party wide defense buff through songs. There's a lot of scope for Bard which isn't being utilized at present.
