That list really isn't remotely accurate. I see more parties reserving slots for SCHs/MNKs than WHM/BLM. SMNs are debatedly a little overpowered but not even remotely enough to warrant a nerf. SCHs are borderline OP on fights with little AoE, but almost underpowered on fights with massive AoE. Paladins and Warriors are about on equal footing now, except when Hallowed Ground is necessary, although WAR takes much more skill to play.
