I'll extend that to saying who cares if a certain combination of jobs works really well together? There's a strange obsession among the players with the idea that every job and every combination of jobs should be equally optimal. Maybe it feels like shit if a certain combination of jobs dominates the top of the speed clear charts, but at the end of the day who cares? If each job is unique, fun, and viable, it shouldn't matter so long as you get to enjoy a playstyle that perfectly fits what you like playing. Unfortunately job identity has been largely replaced with role identity. Healers feel the pain from this most of all.
