Right now I am at 6 Days and 15 Hours on my currently Level 56 Troll Hunter on the PvE Server,
Spent quite alot of time on Professions but I've put them on hold right now to grind the rested XP I've got
Also, this is the fastest and still enjoyable way for me having followed every step of Joana's Guide as I am pretty damn terrible at Leveling ^^
