Makoa's hook has a misleading left hitbox, so aiming slightly to the right will ensure a hook. Try moving to the left or keeping a wall to the right to make it harder for him to land a hook.
Never challenge Makoa.
Except when you have Crowd Control ability. ( If he dont have LEVIATHAN legendary card )
Or keep a long distance from him while shooting.
It is possible to stun him and kill him in ancient rage. So any crowd control ability can pin him allowing you to either move away or let the team focus damage on him.
