I'm not sure how it's been for other players, but it was really, REALLY bad for me. Delay and framerate were serious issues, especially where combat was concerned. However, I have noticed a remarkable improvement. It's night and day in combat, seriously. I just can't believe it. I don't know what they did, but I can chain together several attacks in a row now because the delay is almost nil, and my framerate has gone way up, too. I'm not sure if the patch had anything to do with that, but it's unbelieveable.
If you liked this game at all and were frustrated before because of lag / delay, I would honestly suggest you try it now. It's like playing a different game all together.
