Evie can be really really annoying for strix because she can fly over to you and it is nearly impossible to win against her 1v1 as she’s fast and its really hard to land shot.
Just go to front line when she comes to flank you and stay with team.
It's tempting to get deft hands when you know you'll have difficulty with flanks, but you should get your reload speed from your loadout instead. This will allow you to get cauterize so you can keep down the enemy frontline and help your tank further
Kinessa's reload is fairly long, letting Maeve pitch damage in for free while you're reloading. If she's the only flank around and your team has other offense items covered, you could grab Deft Hands to help out an engagement.
using your transporter is a good way to avoid being killed too much, but taking advantage of the Lie In Wait card is good when fighting against Vivian or other similar characters. Just run and hide, use oppressor mines to sneak in damage, and heal.
