During Ash's Ultimate ability she is not CC Immune, Makoa can Dredge Anchor her out of her area and Bomb King can stun her with Grumpy Bomb. If she has the Battering Ram legendary she will use this to escape the stun and therefore be out of the area!
Bulldozer will be your best friend. Anything that cripples as she get low on HP is almost necessary. CC reduction is also gonna be a big difference. Take out her foxes first enemies second, her healing is very solid so focus on her not the tank.
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.
