There's a funny thing about balancing utility with straight power: If you have both, you automatically become OP. Some players remember Ninjas before the nerfs? They had top-tier damage AND crazy utility in the form of Goad and Trick Attack. Why would you take other jobs when Ninjas had the best damage AND could stagger multiple Trick Attacks for everyone?
And this is why Bards are the way they are now, because if Bard mains have their cake and eat it too in terms of DPS output, they will be the only job in the game worth taking. I mean why would you bother with melees or even offensive casters if a ranged could bring literally all of the damage AND their utility songs?
