Drogoz's tail and horns are included in his hitbox so if he's far away, aim a just little higher than normal. This will prove helpful since you can shoot him once while he's not looking, and if he decides to ascend, you'll be able to catch him.
When Sha Lin plants down, reflecting becomes very easy so sha lins will have to take you out with their primary fire. Stay in the air against sha lin as he is a projectile hero also because he can stun you if you're on the ground.
