Of course people are going to rush to the end. That’s what people do. The great thing about Classic, though was that pacing was an option. Everything was an option. Do it or don’t. You’re not funneled through anything.
You weren’t stalled by a prescription of dailies and several patches for basic and expected features and the end-goal for most was not LFR. Your behavior wasn’t moderated in a way that stifled creativity.
This is the new Blizzard. They’re going to screw this up somehow, but classic was freedom and that’s why I enjoyed it.
