If Evie uses her Ice Block to heal herself or to avoid damage, you can scatter Sticky Bombs around the Ice Block so you can hopefully kill her. Good reaction time is the key!
Salvo does insane damage to your shield. Wait for Drogoz to use his Salvo before pulling it out. If his team is not focusing you, you might save your shield if they decide to push.
If you have Chain Reaction legendary, place some Sticky Bombs around Evie in Ice Block and time your detonation right, so you can punish her for staying in it for too long.
