Too many one-sided losing matches in mixtapes.

I honestly can't even remember if they use sbmm in mixtape. But even if they do, it's still a low-population playlist and those are always prone to blow outs. It's been this way in competitive multiplayer shooters since Halo 2. It will always be this way. Stick to Team Slayer. Don't play Shotty Snipers. Or, translated into Respawn, stay out of any lobby that isn't battle royale trios.
