I guess I was lucky last night. I had just purchased the standard edition from Amazon, got my download code, updated my v1.0 character (yes I know I could have just waited another day and a half without buying another copy, but I was bored and curious), and got put in a queue of about 24 people. 3 minutes later and I was in the game playing. (This was around 9pm EDT)
While there were aspects I loved about v1.0 it was an absolute disaster for UI, quest structure, and more. The key difference from the couple of hours I got to play last night: The core game underneath is much MUCH better, so even if they have access issues the first few days/weeks, it's a game I'm excited to be playing, and THAT is critical.
The graphics are even MORE beautiful, but I can actually run them on high, the UI is pretty good, and I can already see so many tons of quests and things I want to do that it is almost overwhelming.
Even if it takes a bit longer to sort the queueing/stability issues I'm still happy because once they do there's actually something here that I can see myself sinking hundreds of hours into, so a few days either way will be a bump in the road soon forgotten.
Regard all phenomena as dreams...
