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.
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!
Maeve has a particularly harder time than most champions with aiming, as her weapons have drastic gravity drop, and have projectile speed, which means moving around unpredictably will make yourself harder to kill.
