Look, I want to tell you something because you're very dear to me. And I hope you understand that it comes from the bottom of my damaged, damaged heart. You are the finest piece of ass I've ever had and I don't care who knows it. I am so glad that I got to roam those hillsides.
when ppl having problems like this, they should inform us about the region they play too, otherwise its really hard to say anything meaningful to it... EU was totally fine for me today. both arena and ranked, I had no problems at all. (playing from phone too)
I've encountered issues logging in this morning in the NA region. It said I was queued behind hundreds of people - based on the last time this had happened to me, I assumed meant that Blizzard was experiencing another DDoS attack. Maybe it's just the patch, though.
