Maeve's mobility in the air is large but predictable. Pounce is her only way to quickly change momentum, so you can always predict the 2 (Or 3) general areas where she is forced to land.
Lead your shots. If you have a projectile, never shoot at her; even in close range you must shoot ahead of her. If you have a hitscan, wait until you have her in your crosshairs to shoot.
Try to double jump on top of your of enemy as much as possible. You can land your daggers easily and it is next to impossible for the enemy to aim directly on top of their head.
