Off Topic: Would have loved to see the PvE realm eventually catching up to the PvP realm in terms of content progression BEFORE the full release of Naxxramas. Creating some "competition" between the two realms.
As much as I think that's not a bad idea, a "natural" progression timeline is much more important to me personally. I want to take my time enjoying every part of the game. And I really don't want the server to be rushed through the content just to catch up to the PvP server within the next 8 months.
