Tip overview

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 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.

While Maeve is very difficult to pin down exactly, champs like Drogoz or Evie don't necessarily have to aim precisely in order to hit her. Additionally, abilities like Seedling are extremely hazardous to Maeve, because they have a very large AoE.

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.

Maeve can double jump, but newer players don't realize you can jump a third time after pounce. Experienced players use this to stay in the air for long periods of time (Rouges Gambit: jump, pounce/jump, 9 Lives, pounce/jump) use stun/cripple for this
