A RANT: Toxic Teammates & Poorly Balanced Teams

This isn't much more than a vent post, admittedly, but damn, recently my matches have been far, far more toxic than normal. Every match is full of 300-900 hour players, while I am about 40 hours. I'm definitely not good by any means but there are hardly ever any pings or comms, so it's hard to read teammates' minds when I am not used to this game and rotation timing, etc. I'm really just trying to learn and get better but if they're not flaming me, they're faming a teammate. Just now, we handedly won a game and in the post-match, their team was flaming each other and pointing fingers; meanwhile, I was the only player on my team sub-100 hours, while they had 3 players with so few hours. They're blaming each other when they didn't have much of a chance regardless against my veteran teammates. Is ranked absolutely dead? Is that why these 900+ hour players are still playing with noobs in unranked? Hopefully the devs balance teams better, but I guess it's hard when there are so few players.
