Tip overview

Shell spin through his potion to dodge damage and CC. Jump from side to side when you see him try to throw his snake. Damage him and hook him for the finisher, even if he uses his escape you should still be able to get him.

Pounce bypasses Reversal. 'Nuff said.

Grohk relies on totem healing to keep himself alive (most of the time). Cauterize should be first priority.

Always try to keep the Torvald occupied. Your Totemic Ward counters Nullify and his Ultimate, and chances are, the Torvald will cast his ultimate as you and your allies are in range of your Totem.

Strix's stealth can make him harder to track, so toss your Sensor Drones out where you expect him to be and reveal him to your team. If you run the Booby Trap talent, the explosion of your drones can disrupt his aim or throw him off of high ground.
