Barick's Architectonics legendary turrets can not only keep track of Maeve whilst she jumps around, so you can always no where she is just by keeping one eye on the turret, but will never miss her speedy self dealing constant damage to a squishy foe
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
Create a loadout that has snake pit II or III in it (probably less if you have two tanks to heal) and practice nailing your stuns. If you stay grouped and land a stun, evie will get deleted. Try to stun her right as she comes out of ice block.
