It's because the holiday season is on it's way. They can't wait for all the google play gift card money and the mindless gamblers who drop their Christmas bonuses on digital robot dolls and accessories. It happens every year at this time because it's getting colder outside leaving people inside and bored.. they understand this and "tune" matchmaking to push sales. It's a pattern I've been seeing for many years now from the people behind this cheating game.

I can guess the response to this if you ever get one. It'll be like "we're constantly working on reducing the occurance of such mismatches but have you considered you're building your hangar wrong?"

Honestly I feel it too.

Our team is continuously working to improve the matchmaking system. While it may not always function perfectly due to flexible balance settings and occasional attempts to exploit it, we are actively developing solutions to address these challenges. Resolving this specific issue requires careful analysis to ensure that any changes maintain fairness without disrupting the overall gameplay experience. We appreciate your patience and hope you will notice positive improvements in future updates.

In tournaments, matchmaking is primarily based on Tournament rank tiers rather than Squad Power, so players with varying SP levels may still be matched together.  

In the meantime, we recommend adjusting your Hangar and teaming up with friends who have similar SP to make the most of the matchmaking experience.

They truly do just copy and paste the same things over and over every year all year long. Same "blah blah blah I'm a stupid tramp" responses. What an awful company.
