Make sure either Grohk or his totem is dead before using your ultimate. Give about a second after the totem dies, so that the enemies' CC immunity wears off first. Otherwise, your Ultimate will do nothing when the enemies have CC immunity.
Run a jump loadout with the card where Impasse knocks you up into the air. Use this to jump onto Kinessa, and then immediately cripple her with Treacherous Ground Warder's Field. She's very squishy and will have no means of escape.
Her skills are noisy, and good evie always take the risk to come near you when u hear some blink/soar sounds be ready for the fight. always know this she might be faster than you but not better damage dealer
Run the Treacherous Ground Talent, and use your Warder's Field to cripple Makoa. He won't be able to use his spin, and this makes him an easy target for your team. If he uses his shield, just stay inside of it and shoot him from the inside.
