...OP you fail to understand that not every class needs to have equal damage output to be good DPSers.

Bards get to move nonstop, and DPS 100% of the time. They have no positional requirements, don't need to deal with melee nonsense, and can boost other's DPS by a great amount. Don't you wonder why so many people play bard? Because it's so damn easy and a good DPS, maybe?

You need to realize that the value of a DPS is not only based on what they can parse by hitting a training dummy.
