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.

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

Sha Lin's ultimate can make him hard to track, but throwing down a Sensor Drone near where he was last seen will reveal him for your team and partially negate his ult.

Ash's Shoulder Bash has a long windup before she dashes. If you have 5 stacks of Darkness, you can use your Dark Siphon to cancel her movement.
