I'm one bubble into level 73 now, almost exactly.
I'd probably be halfway to 74 by now, but I did a Molten Core run this morning as well because one came up in the LFG channel and I still want the Ancient Petrified Leaf. From what I've read about it, this quest chain qualifies as a genuine Rite of Initiation for a Hunter, and I still haven't done it yet.
So my levelling is progressing slowly but steadily. I will reach 80 in due time; probably in about another week at this rate, as I am trying to average one level per day.
