I’m under the impression that Bungie tampers with individual accounts and their matchmaking, drop rates, etc. Hear me out, suppose you run into a Bungie employee and you bag them. They pursue a malicious action against you by interfering with your specific account matchmaking, drop rates, etc. I think this a possibility because when I team up with others vs playing on my own things drastically change. It could be a far fetched idea but it’s my stream of consciousness and my experience aligns with the hypothesis.
