This works with all Monsters, but it’s best with Meteor Goliath and Gorgon as they have multiple ways of inflicting DOT.
Don’t leave the incapped Hunter alone. Hit him/her with one or two attacks and then attack the others. When the Medic stops healing, then focus on the downed Hunter. Stay on the move. Again, if the Medic is Lazarus, kill him first. He can bring Hunters back from the dead and remove their strikes. Try to use DOT abilities on him a lot so you can see him when he cloaks (a cloaked Hunter that’s been hit with a DOT attack will look like walking fire or acid).
Depending on the Support, this can make your game harder. A decent Hank or Sunny will keep shielding for as long as they can, protecting the Medic while the Assault and Trapper attack you.
