Khan can prevent Fernando from protecting his allies with Commander's Grab. It will cancel his shield and displace Fernando behind Khan, meaning he must waste his Charge ability if he wants to be back in the fight.
Flying Lizards got you down? No worries! If He flies next to a wall hit Him with a slow shot. It should make Drogoz fall due to the drop in speed. Try to bait out a Salvo and Weightless out of the way. Making Him waste an ability and need to reload.
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.
