Any good Drogoz player will open with a Fire Spit and Salvo combo, you NEED to get away from this as it has the potential to do 2,400 damage. Use FrostFire glide first to escape this, and then pick him off while his gun is on its cooldown.
Ash is super annoying to deal with. Her damage output is surprisingly high for a tank, but only at close range(unless they have slug shot). pick her off from a distance if at all possible. if not then wait for backup, you Will need it.
