When Inara is using the Treacherous Ground talent, keep your distance from her. If you get caught in her Warder's Field then you'll have no good way to get out.

Take notice of when an enemy is marked by Corvus, as they will receive healing at any distance any time Corvus heals. Corvus's heal is also more effective when used directly on marked targets, so attack unmarked enemies to force him to shift focus.

Ruckus is vulnerable when he uses his ult. Remain out of his focus and shoot him down.

Assuming you don't have more important targets, hold your ult for when Vivian uses hers. Tag her with a bit of damage, then ult. Be wary of supports being nearby, or if she's running the Scapegoat card, as either will likely shut down the kill
