Me: "Man, I hate Strongholds." 343: "Every other Arena match is going to be Strongholds for you."

Me: “Oh, now I have 3 Strongholds challenges. At least it would only take one or two matches to do all of them.”

343: " We have removed Strongholds from matchmaking ."

Seriously though, this happens a little too frequently to be mere coincidence it feels like.

Tin foil hats on, there is a lot of this happening like there’s an algorithm that makes it harder to get matches that you need. Whether that be gametypes, weapons, or decent teammates to win matches.
