Look at Archer/Bard like Corsair in FFXI

If you haven't played FFXI, it works something like this. Your main focus is to keep front line and back line with the appropriate buffs up. And in between buffs, if you've spent time on decent armor, and equipment such as cards and bullets, then you can shoot for damage. No one's really going to be blown away by your output, but you know you're going beyond an average corsair.

Give or take, I think this will be the concept of Archer/Bard. Likely a bit more focused on damage output than the way Corsair was balanced.
