Interesting blog post on why one guy isn't rushing to level 70, while apparently his son is...
What are you going to do at 70? Attunement quests?
When I called my son tonight to see how things are going back at home, he told me that he is almost level 70. I was shocked. Actually, I said "What the fuck?" He laughed and said, "Yep I'm 3/4 into level 69 so by the time you get back I'll be 70." And he proudly announced that he'd be buying the first tier flying mount tonight. Needless to say, my jaw dropped.
When I commented that with only 2 other 70s in his guild he'd have time to level his Paladin, he replied that he still had a lot to do at 70, like all the reputation for attunements. It seems that the instances will not produce much XP (so much for that lie), so you'll need to quest for maximum XP effeciency then head into the instances to grind your repuatation. In addition, he wanted to max the professions this time, since he'd been handed a toon with completed professions - he opted to level the Warlock I'd given him before his own 60s. Guess he's found that actually being able to supply yourself with something in the way of professions, is actually beneficial. Go figure.
