One of the things that always bothered me a little about World of Warcraft was how quickly new stuff seemed to come out. After any patch or expansion came out you would only just be getting into the swing of things when suddenly the next stage was announced and then tested and then released.
Case in point. During my time playing through the cold wastes of Northrend I managed to raid occasionally, but went through guild after guild as one by one they split up, stopped raiding or just stopped playing. So when I finally manage to get a good guild I thought I might finally be able to get to the end-game content. And then Blizzard announces Cataclysm and so I suddenly have a time limit on killing the Lich King before it will become obsolete. Still managed though… SPARTANS!!!
