I swear there is SBMM in the standard random match, while in Slayer and fiesta you can have all skills, meaning you can have some reather interesting games like one of the ones I was in we had a player who couldn’t get kills to save his life on foot, but damn he was good in that ghost.
Another match it was a race against the feeder on our team, but the enemy had a player who started to do it as well.
I have also run into less of those try hards who will do everything they can to ruin the fun. I mean the last match I was in had two players aiming for each other with sentinel beams and nothing else while the rest of the players killed each other. Both players got 10 kills and swapped weapons. it was interesting.
