The Emperors vs The Dissidents

You overestimate how well a bunch of people who don't know one another can coordinate their saber strikes to be very useful in groups.

There's no way the Emperors take this. They have to take on 3 insanely powerful force users each.

Assuming the Emperors split it evenly and take on three each, they'll lose. Any three of the dissidents can beat either Emperor.
