*sigh* Why do so many people parrot this back? Honestly, what zone you choose to level in -- especially since the nerf to how much XP you need per level -- is very much a matter of personal preference. YES, Outland is awesome, and Northrend is also awesome. I'll be the first to say that Wrath quests, zones, etc. are -- as a whole -- the best WoW yet.

BUT: Don't eschew the "old end game" content just because you can! Especially don't do that your first time thru. Winterspring and Silithus, old though they are, are two of my personal favorite zones in the game. Silithus is unlike practically any other zone (although its plot is hinted at in other zones in southern Kalimdor), and it very much leads into one of the plotlines running through current Wrath content. Skip it, and you'll miss out. Winterspring is just a lot of fun, doing quests for furbolgs, running around the frozen wilderness (hinting at Wrath a different way, lol), and killing owlkin like there's no tomorrow.

The Plaguelands, by contrast, are two of the ugliest zones in the game. BUT, they have some of the best quests. Start the one in Winterspring to find Pamela Redpath in Eastern Plaguelands late at night, and you might find chills running down your spine. They're very good!

Also, some of the old dungeons are a lot of fun. If you've never run Blackrock Depths, you really should. It's very size DEFINES "epic." It's like three Ironforges run together, filled with mad dwarves. It even has a tavern in the middle where the patrons are neutral, and you can sell your vendor trash to the bar tender. Who can hate a dungeon with a built-in tavern?

All the encomia aside, it really is up to personal preference. I say, give the old zones and dungeons a try before jumping through the gate to Outland. If you end up finding it not to your liking, then go out, buy Burning Crusade, and try out Hellfire Peninsula. It's up to you! That's part of the fun. Don't skip things just because others tell you to. I've found some of the most fascinating parts of this game by going where other players told me not to bother. ;-)
