I just leveled a mage to 55 barely and it only took me about 10 hours, between doing random BC/LK dungeons and questing. That’s pretty slow for me, so 80 in 2 days is nothin to brag about in retail.
Now do the same in Anniversary or SoD without any boosting and then I’ll be impressed. I’ll even change your socks and call you King for a day.
