Well, I was doing pretty good in a match of SWAT on uncaged. I was flying over the grav lift and saw an enemy just below me, I had him perfectly lined up for a headshot. However, it turns out that when I pulled the trigger and killed him, my teammate was about half a second through an assassination and I got a yoink. So my butthurt teammate chases me and betrays me.
Moral of the story, go for beat downs and stop getting butthurt about yoinks
