Generally each job within a role should be in a roughly fixed position on the sliding scale of Group output vs Personal damage. Dancer is obvious raid output, displacing bard to be in the middle. That means Machinist should have the least group output but the highest personal damage so its overall dps is on par.

Note that I never said it should have NO utility. Imo all jobs should have some form of raid buff, and the more utility a job gets the lower its personal damage to balance
