I'll be boxing two chars to start with, would two bard/bow-types work or is that not enough buffs, healing, and dps?

I've been planning to go either warrior tank/ cleric heals, or double cleric dps/offheals, but I've also been thinking about trying the bards everyone is so excited about.

Not a big PvP'er, I'll focus mostly on PvE, so maybe that would swing the choice away from bards?
