WoW-Insider called the latest patch a disaster. I would not go that far. Sure, there were some bugs left but there were also a ton of changes. And some issues like the lag were there before the patch. I personaly did not have that many problems yesterday when the patch hit here in germany. We went to raid Naxx and were able to start on our scheduled time. The plan had been to start later to give everyone a chance to install the patch and get their addons updated and running again but since everyone was on time it was not necessary.
There still seems to be a lag problem in instances and so we stopped at one point and moved over to Sartharion. There, lag was not an issue and when we went back to Naxx after that, it went a lot smoother. My guess is that a lot more guilds are raiding nowadays than were before and that is causing the lag problems. But if that was the case, could Blizz not just add another server or divide the instance servers by faction?
Aside from the raiding I had only little time to experience all the other changes that the patch brought. As a miner, I certainly enjoy that I now have to spend very little time on one node before moving on. But on the other hand I had the feeling that there were less nodes available since the other miners are now also able to cover more ground in the same time.
