Be very careful of Khan ult, as if Inara gets thrown off the map, she has no way to save herself. You can use the Mother's Grace talent to give him fewer chances to attempt to grab you, otherwise play carefully with lines of sight.
In a straight DPS fight, Vivian does more damage than Zhin. If you have Deflector Shield up, you're likely to win the 1v1. Be wary of his ultimate and Whirl, as both will ignore your shield and the latter can place him behind you.
Try to keep track of Androxus ult, particularly when your ult is either ready or active, as Andro can burst all his ult shots on you to kill you and/or destroy your drones.
