There’s always that weird chance the player stayed in spawn, got a hit off an enemy and let their teammates get the actual defeat. Gemini Jester would be an easy way to do that, you just have to be within radius and it counts as a defeat as long as they are disoriented. Stasis Turrets could also be capable of being super passive and get a lot of defeats. Scratch that, just seen they had like 39 precision kills. Sounds like a sniper who camped hard.
