The argument"MCH/Bard have utility so their damage should be lower"

[Viviza]

Let stop pretending BRD buffs are THAT special without their own unique/special weaknesses.

Except that we do have to make this assumption based on previous experience. Bards in 2.0 were overrepresented and stacked in raids because their buffs were highly desirable and their DPS was equal. They had to be changed to allow other jobs a place.

Additionally you have a recent dev post discussing this anyway. The position of brd/mch dps is intentional, to offset their utility. Fighting against the very purpose of a job is not a fight you are going to win. You'd be better off accepting the advantages and limitations of the job you enjoy, or picking another job that you can learn to enjoy.
