We knew the raid wouldn't be released this week. We knew flying wouldn't be unlocked the first week. We knew assaults wouldn't be available at launch. We knew the Class/Mount quest chain would take 11 weeks. I'm sure there were other things mentioned in the Q&A last week and blue posts.
The only thing I expected first week that's not here yet was to start class hall upgrades. I've played a few hours each night since the patch released and still haven't seen most of the content.
