The situation is even worse here. I have an amazing net connection (Can host in other places with less than 30 ping), yet SEVERAL times in the past x days connection is getting broken off IMMEDIATELY after the warning message shows up; I do not even receive a split second to attempt to reconnect it before my ranking points go down the drain.

I have exact the same problem. Lost about 10 games this way not fun anymore playing like this wondering when it will happen again and again.
