I hit 58 early saturday morning and was originally planning to stick with Old Lands until 60 but because my gear was so crappy from being boosted to 55 I took the plunge and went straight to the outlands. I deleted all my old world quests and I'm not turning back now. Yes it would be nice to have a ton of extra zones at 70 I can quest in for the cash but I figure the ability to do dailies x 5 is going to be a faster way to make cash.
