So Bonus tier of Defense of Dathomir Dooku is basically immune to My Thrawns Fracture he still counters and he still gains Protection i cannot beat it. I cant do enough damage to him when under stealt...
Daze helps. Healing immunity does too. I usually run an empire team with death trooper. If you wanted to get cheeky, you could use a zeta Vader lead and just let the dots pile up until you can get off a massive culling blade.
