I'm pretty sure it's latency & server-side lag. I had matches earlier where I'd get hit by someone around the corner a good 1.5 secs before they came to me around the corner and casted it. I also played 4 years ago, and it didn't lag at all. None of these issues, and I had a far worse PC back then. From what I've experienced, PvP is horrible in this game currently unless, probably, you're close to 1 U.S. server location. (I'm in mid-Florida) With the US servers only in Virginia, I'm betting PvP is only enjoyable for those close to Virginia. Anywho, I won't be logging in anymore.
