I won three games in a row in slayer and got deranked
You can’t de-rank after a win. You can after a loss. So perhaps the 4th game you played, you lost?
Your game history doesn’t necessarily reflect this claim. Would need to see some video or something as ecievide. If you win and derank double tap the home button and hit x and record it. Otherwise I call shenanigans…
Yeah unless you quit a game then won a game, I can see you deranking
If you have any queries about the ranking system or your game history, feel free to post in the Matchmaking Feedback thread that is pinned at the top of the Matchmaking Feedback forums. Thanks
