Mal'damba is the best healer for duels, if the Androxus is foolish enough to get close to you where you can comfortably hit your shots and the reload stun you CAN win, but if he doesnt good luck waiting for respawn.
Bombking because of his large detonate area doesn't really need to hit meave in order to deal a lot of damage to her and Maeve only has 1800 health so with the right timing you can destroy Maeve
Mal'Damba is strong agains any flanker if played right, if they dont have cauterize, and you force them to fight you in your gourd is quite easy to win against most of them.
Inara is the best frontliner counter for Makoa in game. Not only her wall is a great way to counter the hook, walling off makoa from point and your allies, her field makes Makoa useless if he hooks her or uses the shell.
