Anyone else heard of the Story of King Sisyphus?
He was cursed to continually push an immense boulder to the top of giant hill, and whenever he neared the top, the boulder would roll back down to the bottom and he would have to start right from the begining again.
This was a maddenning punishment from the Gods that causes a lot of philosophical talk even today.
The thing is, this IS what Warcraft is, you constantly strive to get the best gear, the best mounts, and beat the best boss, then before you know it, the boulder falls down the hill, a new tier/expac is out and you have to start the whole process again and again and again forever.
Maybe this is why people get upset about other people having mounts etc that they worked hard to get years ago, I myself find it depressing just visiting Icecrown and remembering all the hard work I put in there. Is it the nature of the game? disuss!
