Welp, time of the day. No many are playing so the match making could only mash you and plats together and call it a game.
Happens to me all the time when I play in the morning.
Or maybe you are just getting better and you didn't notice. [slayer-jinx-wink]
I'm in that same boat, but usually its plats that were boosted and are now tanking their elo, and high golds
Normal or Ranked?
It's liable that they were duo'd with someone in gold. I checked your match history, and only found one ranked game with a plat 5 in it, your team also had a plat 5. Beyond that, you're on average going against high silver-mid gold players. With it stating that your MMR is approx. Gold 4, this seems expected.
Just lose a couple of games and you can easily fall from facing diamonds in to facing bronzies.
I fought someone in master and I'm bronze
