When Zhin has his Counter stance up, take the time to reload your weapon, switch targets for a moment, or escape if needed , as you'll be hard-pressed to damage him while he's Countering.
Makoa's Shell Shield will not protect him from your Barrage if you call it down directly on top of him. Watch out for his Dredge Anchor, though, as he can still grab you while you're channeling Barrage.
Shell Shield has the longest base cooldown time of any shielding ability and Makoa lacks a Legendary card that reduces its cooldown. Shoot down the shield when possible to ensure its usefulness is limited.
Dragon Punch will inflict no damage to you as long as you stand in your Assert Dominance field. Be sure to hit the ground and plant your flag before you get punched though, or you'll die in midair.
Unless the enemy Barik is using the Fortify Legendary card, his Barricade only has 5000 Health. It can sometimes be more advantageous to simply destroy the Barricade instead of sidestepping it.
