This is just silly hyperbole. It's 100% about you wanting easy games against terrible players. Let's at least be honest about that. You're not stuck with players from around the world often, and nobody is reverse boosting
If they are that's just stupid because they matchmaking considers you last subsection of games to determine your skill, so reverse boosting would only get you a few games with bad players and then you'd be right back with your normal skill. I have 3 days played and I've seen precisely 0 people reverse boosting, so this "in almost every lobby" stuff is total garbage.
I'm sorry you can't get 3 chopper gunners a game and actually have to play against people relatively close to your skill level. This is something I will never understand. I doubt you play your sports games on rookie mode, or narrative games on easy, so why would you want that in CoD? Isn't overcoming a challenge rewarding enough?
