idk what it is, maybe i'm more relaxed or maybe just going against all the mlg "pros" in arena, but I do a hella lot better in Warzone with gun play and over all performance
... like giving me a double kill after shooting 1 person or a person dieing 5-10 seconds later after being shot by my dmr after I've been killed.
Probably a result of accidental friendly frags or shooting.
As you probably know - but I'll say anyway - once an enemy player has been shot and damaged by you, if their team mate (the enemy) shoots/frags them, it will not count as a team kill but as a kill for you.
Not really accidental frag from me, I know when I'm throwing grenades. I've literally seen this happen a few times and the 2nd enemy was nowhere to be seen, in some cases it's the same person I just killed.
Obviously not from you. I mean an enemy accidentally friendly firing/fragging their own teammate (an enemy killing an enemy teammate, after you've already damaged them some).
Also, if you damage an enemy without killing them, if they accidentally kill themselves (fall off the map, frag themselves) it will still count as your kill.
Try watching your matches in theater mode to see what really happened in those situations. I've never seen one that couldn't be explained.
