Shards in Europe

We would love that, but it's entirely out of our hands, as we use Firebase to power those shards. The good news is they were acquired by Google and are in the process of transitioning to Google's infrastructure over the next year. My guess is that they will roll out shards worldwide "soon" as a part of that. When they do, it will be very easy for us to provide better latency to users outside the U.S. As you said, I think right now it is playable, but you're probably looking at 500ms+ latencies instead of the 150ms latency we target in the U.S.
