Exalted with Darnassus by level 30
I started a new Draenei hunter recently and decided I wanted a kitty instead of an elekk when I hit 30.
Here is the route I took:
Crash Site: 1-6
ALL the rest of Azuremyst Isle: 9-12
ALL the rest of Teldrasil, and the few Darnassus quests I could do: 13-15
Bloodmyst Isle: 15-22
Ashenvale, Blackfathom Deeps, and Stonetalon: 25-29
Most of Westfall, and some Duskwood and Redridge for the spillover for the last little bit I needed: 29-30
I did EVERY quest I could find, and there were a few hard to find ones. The level range I was in is a guestimation as I don't quite remember the specifics. There were some level 30+ quests in Ashenvale I didn't do, about 4. If I had, I prolly would have not had to do much if any spillover quests, but I didn't want to get *too* much xp and ding 31. I also did not turn in the final quest in Raene's Cleansing, as I wanted to keep the rod.
When I dinged 30 it was only TWO spillover quests later that I hit exalted.
Cost: At level 30 and exalted, the training was 28g and the mount 8, so a total of 36g.
