After spending more than a full day of trying to get through Raubahn's Wall, I was lucky enough to get past it. On the other side of the wall I found that the expansion is very good! The MSQ is enjoyable, lots of side quests, areas to explore and tons of things to do. The game DOES live up to the hype once we can get past this unfortunate set of circumstances.
To those who are still behind the lines, don't loose hope or give up. The reward IS worth the wait, you will see once you get past the wall.
P.S. Please keep the discussion about the instance issues in the existing threads.
