People talk about the multiclassing but really that’s an easy way out of talking about the real issue. We cannot sidestep the fact that this is real and plenty of people have this experience even without changing classes every game. Below is a screenshot I took about a week ago, no multiclassing involved and is even worse than OP’s experience.
It’s a ten game losing streak – after about 6 or 7 games I just felt like something was going on that was clearly outside my control, I wanted to continue queueing up just to see how long this will go on for and if I can get to that magical 10 number and seeing nothing but losses on my screen.
Look at the results – out of 10 matches, 7 were what I’d consider complete stomps (500 to around 250 or less), with some outright embarassing results that you’d expect from Silver vs Plat. A single game was close, out of 10.
Matchmaking has an issue. I don’t know what it is exactly, but it’s there, we can sit here and pretend this is all a “git gud” issue all we want but this kind of thing points to a larger issue whether you want to admit it or not. It’s extremely streaky in my experience, and seems to go on a kittening crusade every now and then trying to “balance” your rating and bring your win rate down closer to the magical 50% mark after a lot of wins.
