The story is not a linear plot progressing over time. The story has 20 different lines of plot, stopping and starting whenever. Also, you need to buy things outside of the game (books) to understand what is happening, now and during the gap between expansions. In short, most people playing the game have no idea what is going on. Will this ever change? Will WoW ever tell a main story and stick to it, instead of telling 20 different stories, stopping and starting at random points each?
