Dimensional Link can also let her travel to the last active illusion spot after it dies, and this can help her escape combat quickly, especially if she has an illusion hidden to heal her team. She is only able to have 2 active, so know their spots!
Watch out for his ability to leave behind an explosive fissure, and stay away from it! This would result in him getting healed and you taking severe damage. Make sure to track him too, so as soon as he is physical you can attack and kill him.
If he has his shield larger with his talent, try to stay on the side they are on without them knowing. This makes it easy to hit them because his shield only stops attacks from the front. (if you are a tank, keep pushing them back past it to hit 'em)
Focus on Inara last, aim for everyone else first. When needed, poison her and get a couple hits in, but make sure to move around so she has a hard time hitting you because her shooting time is slow.
Ying is able to teleport to her allies during her ult, so when she does try to kill her on sight. She can still have her ult going after she dies, but it can make it harder for the enemy to be healed. Also, remember she can teleport multiple times!
