Simple really - the screen effect from having max stacks of forceful makes it impossible to see properly, reduces your effective fov, and if you’re sensitive to it causes actual motion sickness, making the whole keystone feel like a gameplay and actual real world nerf to your ability to even play the game properly. The melee justice and ranged justice buffs don’t have the same problem, and the screen effect makes it feel like that keystone is the only actual viable option of the two.
