Why do Bards have the highest DPS?

[Xquiel]

actually bard is probably the lowest potential dps but the easiest to achieve making them seem incredibly overpowered in low end play

In high end content groups basically only bring one bard for songs because they are the actual best part of the class

I've done titan a lot of times and bards always are in the first place in dmg, ahead from DRG>Monk. They have advantage because they have the easy job, spam skills while running away while monks have to keep 3 DoTs on the boss, greased lightning 3 and one extra buff to do less dmg.....
