I think the best memories for me are easily the days before I raided. The game was new, purely about fun and not results, and I was calling the shots in my own guild full of fun people =) Then I left the game for a bit and when I came back we decided to disband the guild in favor of raiding, and things were never quite as fun. Not to say that raiding isn't fun, but there's a price to pay for getting those nice purples.
