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.
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.
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
