I quit wow a couple of months ago. This part you said pretty much sums up why. It just isn't the same anymore and I don't ever see it going back to that way. And what you said about the skill part was dead on accurate. That's actually how I met most of the people I ended up spending time with in-game and raiding with. The game's community now tho is just awful, not that everyone is personally awful, but it's just infested with many people who are just not very good, not very nice, and pretty much just provide nothing to the community besides negativity.
All in all, it was a good run. I am glad I stepped away though.
