Immortal will make Fernando invincible, even to Dragon Punch. If he's hit, Drogoz will put Fernando down to 1500 health, and Dragon Punch will be cancelled.

Salvo does insane damage to your shield. Wait for Drogoz to use his Salvo before pulling it out. If his team is not focusing you, you might save your shield if they decide to push.

when drogoz ults, use your ult just before getting hit by it. it will counter it.

If Fernando doesn't have his shield up, try to hit him with your spit (don't detonate it). After it hits, you do more damage to him with your rockets, taking him down faster.

When Fernando activate his Ultimate to counter yours, try to aim for his teammates that is not in the Immortal radius. This way you wouldn't waste your Ultimate.

Remember to use your ultimate after his is on cooldown, otherwise he will not die, not yet amigo.
