If the healer asked to turn it off than that means the healer doesn't need it. Therefore it would be better to turn it off to deal more damage and kills things faster. If the healer messes up that's on the healer. It has nothing to do with other bards refusing to sing when it is actually needed. There are no hybrids, every other dps has support skills that they can utilize when its necessary. As DPS you're there to have the mindset of finding out what is the most effective way to put out the most damage you can do.
