Im not 100% sure, but it appears as long as you actually kill the LAST enemy with a normal attack it works. You can get dot kills, but the final blow has to be a player attack and the enemy die from damage. Very low sample size of 6 ppl so hence the not sure. It works with a JMK team and no damage over time or thermals if you want to be sure. Theory being the dot death of the last enemy kills them and ends the battle before the Victor is applied in the code to determine if you got it (even though it shows visually).
