Nightsisters invincible

I still use EP lead (no Revan or Treya yet) DN, DS, Thrawn and Nest and I hunt these squads. Most reliable wins I have and they are everywhere b/c I guess they destroy jedi. I clear taunt, fracture then eventually annihilate Talzin. Rest can take time but without the plague going bonkers it's not too bad. If you can manage it I find it helps to whittle a few of them down close to yellow/red then try to kill them all quickly in succession. They are normally not very fast compared to other meta arena teams so I find them easy to control unless plague starts spreading.
