I also think, note - think not claim, a lot of people feel the same as I do, from what is heard inside the game on chats and so.
Also; Yes friendship inside the game has some value for me and it is what keeps me playing lately, I can spare 13EUR per month I can spare a lot more, I also invested a lot in my characters so yes in a way it points to addiction when I try to drag myself to unsubscribe, but once done I have no problem to live without Warcraft as I did many times when the game got stale, while waiting for patches - that said, the game was never so stale so soon as Cataclysm.
For the daily zone; I guess people have different opinions. For me doing the same quest more times is a chore and not something I would label as fun. I do pretty much the same thing at work every day, as most people, so I don't want to fall into that routine inside a game too, where I "should" have fun. If they can design 100 quests for this patch, I bet they could design 5 quests/week and patch the game with new quests frequently. That way, I could look forward to do new daily quests each Wednesday and get the grind done with fresh stuff. Those quests could easily be added to the total pool, so guys like you who don't mind doing them over and over again, could do them each day from the point of implementation if they desire.
