The same exact argument has been made by casters where they feel that a BRD is required in their group to do the best DPS because Foe req is too strong, also that groups with ninjas needed a warrior to do max dps because not having to use dancing edge is a huge increase. The game has synergies and always has. Unless they wanna homogenize everything and take away unique buffs, we'll always have this problem as long as their are more jobs than spots. Even right now, some will argue that RDM is required because they have possibly the same potential output as the other casters but bring a physical dmg dps buff and now SMNs are the only ones that bring old Foe Req
