IM PLAYIN discusses why Vault of Glass is a true MMO experience, and how it's supposed to be so tough.
"If there is one thing from WoW that I have had serious withdrawal symptoms from, it would have to be the raids. Not only because they were great times that really challenged the player, or the fact that they were so different from standard instances, they brought specific challenges to boss fights that would not be anywhere else in the game. It was a wholly different experience. They also separate the idiots who didn’t know how the play the game from the pros."
