Well, they did say that Archers will be capable of burst of damage, which hopefully if designed right would mean that when Bard comes, the buffing will take place when your burst cooldowns are down. So to be effective Barchers, we'll be doing buffs, and our DPS will be coming in the form of burst in between the buffs.

If the burst damage is significant enough, we may not be the top DD, but keep up with the pack, or at least contribute. (As of now, Archer dps is pathetic.)
