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.
Do not rush the objective when there is a deadzone placed. This means playing passively and prioritising targets on the enemy team while waiting for the deadzone to disappear. Once it's gone, the team can group up and start to slowly cap the point.
