When dealing with Strix, it is paramount that you get the jump on him. Try to aim your Net Shot during Heroic Leap, and with Ensnare he'll go down fast. Strix has the lowest walk speed in the game, so even in his stealth he won't be moving too much.

Don't solely rely on In Pursuit to take her down. Use Combat Slide often to reposition yourself; it may help you avoid a Pounce. Missing could mean death, so don't jump or spamclick, as those lower your accuracy. Death Hastens is ideal against Maeve.

Void Grip makes him an easy target for your team, although it also leaves you vulnerable to his Grumpy Bomb. Void Grip him when you can quickly escape behind a wall so he or his allies don't punish your open defenses.

If Grohk uses Spirit's Domain, his lightning doesn't hit through allies, but his Shock Pulse does. He may try to stay in the front if they group to get some damage in, so use that opportunity to burst him down.
