I suppose the redeeming factor is the single quest hub. Having pretty much all the quests in one place makes it a little easier to deal with the zone. Still, next time I level a character through their 50s, I think I'll focus on Burning Steppes and such. I've heard bad things about Silithus, too, but I've never been there with any of my toons, so I think the newness will make it acceptable.
As I was questing, I noticed that I consumed all my rested experience while in the Crater, which will slow me down a bit. Not too much, I hope, as I really would like to make Outlands by next week, especially if 3.2 hits live then. The only thing I still need to do is level up my mining skill. Right now I'm woefully behind, only just hitting 166. As I'm questing, I see lots of ores that I can't mine because I'm not skilled enough, which is frustrating, not to mention stupid. My professions are for making gold, and right now I have to pass up all that potential profit. Gevlon would be very disappointed.
So the "to do" list stands thus: mining, mining, mining (need to hit 300 before Outlands); quest, quest, quest (three levels still to go); sell, sell, sell (I'm going to need gold for my next riding speeds, as 3.2 comes with cheaper fees, but still substantial for my reroll); and fun, fun, fun (it is just a game, you know!) ;)
