Before it's added that "SE doesn't balance around dungeons", they may start when Criterion hits since they're supposed to be difficult content for 4-man groups. Nobody wants to see a tank nerfed over Criterion, so I'm sincerely hoping they do a few things to make every tank viable. Such as the bosses actively challenging the tanks full kit so every tank feels like they're giving it all, mobs where Bloodwhetting doesn't trivialize them, and hopefully looser DPS checks (see P5S and P6S) where the difference in tank DPS doesn't result in some tanks being taken less over others.
