I have a fairly fast PC (fast Intel Processor) and high speed internet (10 mbps) Saturday was the worst for me, kicked out of battles continuously. Sunday was a bit better but the lag was worse than I have ever seen. I had a Ping as high as 900 at one point! Normally sits at around 142. While I am here, my FPS rate is typically very low when I join a new battle, somewhere between 18 - 38, which seems to resolve itself after a few minutes. This has nothing to do with the lag experienced this past weekend but has been an issue for some weeks. Today, strangely enough, I have not had the same problem.
