The important things when you face andro when he about to engage you are to Keep Calm, Dont Panic, Give damage and place teleport for escape. Remember 2x of your normal shoot, enough to make andro retreat. Dont Feed andro reversal, wait for it.
Dredge is not weak against drogoz. You still can play inside buildings or house and give spam.
If drogoz about to enter buildings/house. Then "welcome to my area".
Max your shield. Place teleport first and try to track evie when she about to engage you. If she about to landing, then spam the landing place. And in duel 1v1 you need to jump or moving right left or both because she might miss her shot.
