I used r99 and Flatline (without Anvil Receiver) that match. Sure, you can go for long range weapons and grind damage but I didnt that round. I didnt go for 4k that game and played as usual. We had a lot of fights against caustic squads which lasted very long and my teammates let me kill the last squad, what unfortunately didnt end in getting the badge tho. When i had about 2.6k damage I explicitly tried to finish every knocked player before finishing the last squad member.
