It helps explain why the guardians/juggernauts got a buff relative to the sentinels/marauders in focus, at least. While they both benefit the same from smash/sweep buffs, the new zen/berserk mechanics in shii-cho reduce the amount of damage that the focus sents/maras can do unless they go all out stacking power, as has been mentioned as imbalanced in this thread, that makes smash/sweep the one trick pony of the spec.

Honestly, if they want to avoid controversy and make the community happy, they should lie about what they play as because saying you play the class that is currently the FotM will lead us to believe that you built it to be that way.
