Blizzard. In patch 3.0.2 the servers were down for what was nearly a day before hand, and when the patch finally did arrive not everything was as it should have been. It took a month's time for all the changes to make their way to the live server.
When Wrath of the Lich King was launched, there were countless servers inflicted with near game-ending lag and connection problems for people. And that's not to mention the hour long queues many of us faced (and still face to some degree).
Patch 3.0.8 brought with it a whole new host of issues, leading Mike Schramm to proclaim The Disaster of Three-Oh-Eight. There are still lingering issues from that. Just ask any Hunter about the cower bug.
So while we sit here with bated breath waiting for new information about patch 3.1, there is a little voice going on in the back of my head. "Do you really want this, Adam? Do you really want your email box to be flooded with tips about how buggy the patch is?"
But then I think of happier things, like clam stacking, and I smile.
I want to take a poll today. Do you think patch 3.1 will be a clamity or a cheering celebration?
