So for how long are you willing to do the same things over the same content with broken classes, broken specs, at the skill level the average player is today? You can never revive the time of vanilla, because this isn't 2004. Mentalities have changed, skill levels have changed, everything has changed. Putting out the same content is the same as those guys who play their favorite game form 10 years ago, once the nostalgia is filled (which for me in Nost servers was filled and over filled at lvl 40) you quit and do something else.
It's not new or fresh and you can't even relive it.
