Yeah, Storm Peaks is probably my favourite zone in the whole game; great quests, great scenery, cool music, etc.
Northrend is far, far better than Outland. Like, Outland looks like a bad content patch in comparison. The only thing wrong with the game now (from what I know) is the PvP balance at 80; it literally is just burst damage warfare, DoT classes and healers are pretty much worthless.
