Written from my own experience
But, never zoom in too deeply. If you wander around you get flooded by detail and the total picture really looks stunning. But closer by it is polygon-city. That actually means that they did a good job creating the experience that lets you look past the dents many computer games have. It has been the experience i have been looking for a long time.
It is the first fantasy game i ever played and i did a pretty good job i guess. But now that time is over. Once you've reached the end game content it can either be fun or be like hell. You get this one option: item farming so you can hold out long enough inside dungeons. The whole item farming brings up the same question a volunteer would bring up while crossing the mojave desert without water.
It just gets a bit sawed off at the end. And as it is with all the games (look at counter strike) the community is transforming. You know there is one race called Night Elves. 90% of all leet-speak comes from that race. The forums slowly get flooded under "nerf" and "overpowered" complains towards blizzard. Won't blizzard know how to balance their own game? A bunch of kids think they know better i guess. No really there ARE kids out there, thousands.
I think this game is best compared to a dream city. A dream city, without something overpowering it like a government. It slowly turns gray and it gets free for all. The bored leave. People that 'own' the place stay, of course. Let's just say if you could kill your own alliance it would be a massacre, that is how gray this community has become.
Conclusion: i played it too long. Either had to be a pro now or had to be playing another game for the last 4 months. None of it happened.
