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
Try to do a dubble jump, pounce upwards, tripple jump, nine lives, punce, quad jump combo. Hit ur daggers and win the 1v1, unless its hitscan or a counter. If that play safe. If the enemy is spread out or someone is low, try to outflank the enemy.
As maeve, do not double jump all the time. It makes u more vulnerable cuz its easier to hit her cuz ur a lot less mobile in air. Instead of jumping all the time, move on the ground left and right, forward or backward. U will hit the daggers easier.
Prowl cancelation is very important to know if using cat burgular. Right before ur about to throw the daggers at an enemy, activate prowl to get the bonus damg.
