So first of, I understand that Bungie is already focused with plenty of things and that they may not get to see this post. But regardless, this is what happened when I went to trials. We had some challenging teams but overall we got to 5-0 pretty quickly . That was when one of my buddies was instantly signed off of xbox live so we were forced to do a 2 on 3. Frankly, we almost beat them and if they didn't cheat , more likely that not we would have gone flawless. I realize that in every game no matter what there will always be cheaters, but take this as a warning: Yes you have to be better than average to go flawless, but in my mind its whether you go against people who play fair or not.
Best of luck man. Unfortunate that happened to you.
Yesterday me and my 2 buddies went flawless for the first time but we ditched 5 different passages after going 7-0 each time and running into cheaters.
