I am starting this a little bit late, but here it is. I hand leveled him to 10. The quests are just too easy in those levels.
Current Level: 21
No sign of detection.
Day One:
I used profile XR Circle 10-15. A lot of gray drops. Sold for pretty good cash. I reached level 15 not taking very long at all.
First 5 Talent Points in Ancestral Knowledge, and 1 in Thundering Strikes.
Day Two:
I used profile Savanna Cats 15-19. I turned loot filter to just Small Filthy Paws(they sell for a good amount to vendor). I looted a lot of greens from this profile. I left for the day and when I came back, I was two boxes away from 19.
Filled up Thundering Strikes
Day Three:
I used profile Northern Barrens 19-21. Very nice XP rate. If you are not in need of money, I would come here at maybe 17. I hit 21 fairly fast.
1 in Shamanistic Focus, 1 in Enhancing Totems.
