IDK if it's insane bad luck, but ever since the new act, I've been losing a ton of games. I've won 3 in about 15 games. It's not even the usual AFK or bad teammates. I've been doing my part and getting MVP or playing my sentinel/controller role well, and so has my team. I've tried 3-5 stacking but same results.

What's strange is that I did have a big win streak before the new act, where it landed me in plat 1. Now I'm gold 1. Could it be possible that I did not deserve plat after all? Some of my friends as high has diamond have also experienced this.
