Maeve can down you in just a few knives. Get Haven and Life Rip for sustain, and save In Pursuit for securing the kill. Discovery will be the best choice to keep her in check, making sure she doesn't flank from behind and poke the backlines.
In Pursuit is highly effective against her. One or two shots are all it takes to let In Pursuit finish her off. Side note: She might heal while you are using In Pursuit should she have Artful Dodger, Patch Up, and/or Savagery.
