Q u o t e:
Never played during the launch of any MMO or expansion--I have always shown up weeks late. From what I hear though, launching a MMO or expansion = instant death.
Is there honestly ANY chance of playing the game come Dec. 7?
As a bunch of people are mentioning, things have gone pretty well in the last couple of expansions. We have learned a lot since we launched the game 6 years ago. There have been some latency issues in the past, but that is often tied to how many people are in your direct vicinity and it improves as players progress and spread out. We have improved spawning timing and such so even if a lot of players are doing the same quests they can be done in a reasonable amount of time.
Things can always go wrong, but it should be playable.
Oh, and if you are on a PvP server, be ready to fight for those quests.
