I’m banned from ranked because I left 2 games when ALL of my other teammates left the game before me because of out of control latency. Excuse me if I don’t want to stick around in a 1v4 so that the enemy team with a huge ping advantage can kill farm me…
This is a prime example of why the quitban is a lazy and HORRIBLE system! Aren’t you glad they tried forcing you to stay in a terrible game?! 
It reminds me of when someone stood on my ghost in halo 1 mcc and the second I got in, instantly it betrays them and they kick me out on purpose.
I bring it to halo Reddit’s attention and ask if there’s anything that can be tweaked to the ban/boot system to prevent manipulation like this to sensitive vehicles and they just lock my post and perma ban me lol
I remember while playing Halo Reach that you could leave 1 match but a second time you would have a ban for 10 minutes. The messed up part about it if you accidentally betrayed somone, and they booted you that was counted as leaving a second time as well.
I get your frustration because 4v1 is not fun, but at the same time, it’s a hell of a lot of coding trying to figure things out, and from what I’ve seen so far with 343 work ethics? Don’t expect things to change any time soon.
One more thing. You should feel lucky that the server issues might be adjusted vs Bungie’s broken P2P from Halo days that they are still using and literally blaming the entire players base for server issues. They are even nice enough to have a little pop-up telling you it’s you that is the problem. That is just an a-hole move because they are too cheap too get dedicated servers and it’s been 14 years 
It is the worst game out to date when it comes to getting discontented that the company should be embarrassed for running a game on that crap.
