If you happen to see a makoa and don't have any teammates on you, just back off and poke him if possible. It won't be long till one of your teammates
Joins in. If so. Take him out toghether and try your best not to be in his hook range.
As @mcdude said. Save your reversal untill she had used her pounce. After that try to get as close as possible to get a punch on her. A decent amount of maeve players freak and use pounce to get some cover before going out again. Chase her.
