Hi there,
I'm living in the EU, and one thing I have to say is that in the current state, proxies are utterly useless.
If one guy can't connect to another, they both get 350+ ping on each other. I understand how proxies work, and as long as there will be no proxies set up in the EU, we'll get things like that.
As of now, anyone connecting to my games with a proxy will be kicked. It's not the smartest move, but at least it ensure a non stuttering game for everyone else.
Oh and only until this is fixed
