Thanks for looking out friend. I am over it gave too much energy on these Apex troll trials. For anyone else considering doing the eva 8 here's what i learned to have a CHANCE of getting credit:
-go for fully shielded and healed enemies.
-don't go for enemies that have been hit by friendly fire
-stay in ADS the whole time or hip-fire only, DO NOT SWITCH mid shooting
-team death match and control kills count
-don't pre-damage enemies or use grenades, eva 8 only
-empty out entire clip no matter if you knock someone in few hits
-do not move at all when shooting so you can keep rapid firing. I feel the knock doesn't count if you say climb or strafe as it halts the rapid fire
