Ranked matchmaking is officially broken

I’ve played 4 hours worth of games today’s just ranked and have had literally every other match down a teammate not only does this actually de rank me but damn is it aggravating. I’ve played other matches where the opponents are down a teammate as well. it worked great up to last week. What the heck happened. Ive got a list of other issues like melee’s not working. Why are all the AAA games now out the gate broken.
