Fast forward 15 days later.
The high latency while raiding places like Naxxramas and Malygos is still there. The servers are still packed with queue. The patch was a near disaster. And we're still getting bug reports in every 10 minutes, both in comments and via our tip-line.
Many people want to know why this hasn't been fixed. People are out looking for blood. The whole head on a pike sort of thing.
A better way to approach the situation is to try to come up with contingency plans and other activities to do. If Blizzard cannot get their servers to work, to the point that many consider the game playable, then people will need to focus on other aspects of the game or try to work around the problematic parts.
On the couple servers I play on many of the top guilds have decided to stop raiding for the night if there are any problems with high latency in the raid instances. On Alex's server people raid only for a couple hours after 10pm when the queues and population have dropped off. And still other guilds I know have just said forget it completely and are on hiatus until these issues are fixed.
