When Drogoz is airborne, try snapping almost directly in an upward direction then snapping to his location horizontally. I do this when playing and seem to easily headshot him mid-air on a regular basis. example: https://youtu.be/DGVWJDimNv4?t=83
If Pip is pressured, you might force him to use his Healing Potion on himself to survive or if he's playing selfishly. Cauterize helps alot in countering him.
USE YOUR WALL! It blocks fatal attacks, (Terminus ult, skye ult, ruckus ult, willow seed, BK grumpy, etc...) Most healers need line of sight to heal. block vision from a single target with your wall and burst them down before their healer can react
If you see Terminus with Seris run for your life because that's a fight you cannot win the best strategy is to either lure seris away from terminus or kill her without terminus even knowing cause he'll try to block all your shots letting her escape
Right before Andro's Reversal shuts off you can send your fully charged shot at him (easy to headshot him when he's trying to position for Reversal) and hit him before the green things are gone. Pay attention to the sound of his Reversal.
