Okay, first off, I'm not the best player in Overwatch, I admit that.
I did my season 3 placement games and ended up at around 1450, which quickly climbed to 1810 in a few weeks. But since yesterday I've been losing four out of five games consistently (and I played 15+), which placed me at 1610 now, a whopping 200 less than what I was.
It's supposed to fluctuate a bit, I'm guessing, but isn't this a bit much?!
