If Maeve finds you by yourself, she WILL go after you, and of you aren't in close proximity of any teammates, she WILL win(assuming she has all her abilities ready). Try staying closer to your teammates or making a system for grouping up.
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.
Never jump back, because you risk to be killed very easily by champs like Androxus, Tyra and Viktor. Try instead on jumping very close to them so they get confused!
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.
