I played a match on slayer with search preference set to “expanded” got into a match and our team got whooped (we lost by 20 points or so). I then did another match on slayer set to “expanded” and I was the same team as before against the same players. What gives?
Expanded will loosen restrictions and find the fastest match available. If you want better matches that are close, search Focused.
I only search expanded when I’m desperate.
