Uh...Well, I don't know what your friends problem was, but last I played was 79-80 in Wrath. And most of my chars with straight play through took about 6 hours. One char I managed to do it in 4. I think I probably still have the screenshot of the time it took too. I'm not making any false claims, its about knowing how to quest there. Here, its not really "knowing where to grind", because the places to grind are so limited. It's, go here, spend 10 levels and 100 hours of your life getting those final 10 levels. That's just ridiculous.
Lol, k.
Edit: Also, it took me about 8 hours, give or take, to go from 140-150.
