I'm not sure considering that PCT's design right now is literally destroying Ultimates and they haven't adjusted anything in fear of destroying the job for other types of content. DSR also had crippling issues with some tanks (WAR/PLD and MCH to a lesser extent) and had no adjustments made either until 6.2, where it showed up again for P8S and... you know the rest.

The real problem is that savage and ultimates lead the whole battle design and dictate it to the rest of the game, and they follow metrics so little and narrow that even going barely outside of the beaten path is a surefire way to break the whole package... Thanks DDR, the 120s meta and the holy damage metric.
