I have been working my way through it. I had hit 50 and finished the main quest when the game first relaunched. I think all the patched in story will take me 3-4 days to complete. Not too bad. I think some of the filler could really be trimmed out. Also, the 2 quests that required me to do guildhests took around 2.5 hours to do because of queues. I think they should be removed completely since it is useless and boring low level stuff.

I could see how people who bought the game to play with friends would be annoyed by having to do it all though. I think making it optional and then letting the player work through it when they feel like it is a good idea.
