i dont even know how you can say this. There are players using this to take half a persons health out in one hit.
When you see it happen coordinate with your stealth team mates. Separate the 3 jedi using this tactic. Two stealth users can achieve this. One will have to sacrifice themselves for the other to fully separate one from the pack. Coordinate you LR DPS to target the Jedi separated. Rise and repeat. It really isn't that hard.
