Don't use any of your abilities until after he puts down barricade. Then, Charge through the barricade and burn whatever's visible until you start dying and put your shield up.

Always keep an eye on Makoa when your shield's up. Makoa's hook will disable your shield if it hits, but it can't hit you through your shield.

Wait until he deploys his barricade. Then, charge through it and start the assault.

Makoa's shield doesn't block damage at very close range. Your flame lance, on the other hand, does. Use charge to rush into range and then roast him.
