The betrayal system is flawed and its intention is to remove players who “intentionally” betray their own teammates. But it’s kind of hard to not betray a teammate that jumps in front of your wraith while you are going 200+ MPH. It’s also hard to not betray your teammate that is throwing plasma grenades at your tank/wraith so he can antagonize you into betraying him so he can have your tank.
It is also hard to not betray your teammate when you have a sniper rifle and your teammate runs in front of you and you headshot him, (yes, this has happened multiple times before /facepalm). It is also hard to not betray your teammate when there is a betrayal system on an 8v8 gametypes called Big Team Battle, which is beyond me why they even added betraying on that playlist.
Furthermore, it is hard not to betray your teammate when you pick up a sniper rifle and they are shooting you multiple times to try to get said weapon. What am I supposed to do? Let him betray me? Lol. I’ll waste a few shots to keep the sniper! It doesn’t take a rocket scientist to figure out that the betrayal system is flawed. Maybe ey know it’s flawed and don’t want to fix it, kind of like the stats that have been frozen for a week straight,
Oh, and it would help if you guys can fix the bug that’s been on reach for a few months, maybe even years: when you get into a helicopter, and are the pilot, and you get lasers by the enemy, and you helicopter blows up, it will say you have betrayed your teammate who is in the gunner seat, but this only happens if the pilot gets lasered!! (And yea this has happened before, and I have been booted by my own teammate for getting lasered by the enemy).
Heck, if your going to add betrayal booting in an 8v8 gametype, you might as well throw it in on grifball and see how many people are playing that playlist after a month. My guess would be, only the people that are boosting on the playlist lol I hope this was enough to convince you guys that the betrayal system is flawed, because I think we all know the answer to that question 
Best part about the betrayal system is it always boots you when you accidentally betray a teammate, almost everytime!!! I got betrayed by he same person 3 times In a row, and I had no option to boot him, I betrayed him ONE TIME, and I get the boot. I sometimes feel like this betrayal system is trying to troll me. I don’t think it was this bad on halo 3 lol.
