From the last post until now, I've changed my mind a little bit. I took a simple travel quest Where in the World is Hemet Nesingwary to the middle of Sholozar Basin, to just meet the legendary Hemet Nesingwary and to do the Ghostfish Daily fishing quest for Dalaran. At least, that was my intention. So, I introduce myself to Hemet AGAIN, even though I've already done bucketloads of his quests in Stranglethorn Vale and Outlands (that dwarf has a memory as bad as my own), and run on down to the River's Heart to catch the elusive Ghostfish.
After I catch the fish, I look around, and I notice a ! over Tamara Wobblesprocket's head that I hadn't seen on the other few times I had done the Ghostfish daily. So, I accepted her Part-Time Hunter, since it seemed like it would be close, and I should be easily able to solo whatever mob I needed to. That led me to the Frenzyheart questline, and then I started doing the Nesingwary questline, since I now had 2 (two) tanks ready to soak up and deal out damage. As long as you keep Hoofing It, you've got a pocket tank with Zepik the Gorloc Hunter. As a hunter, I already had a tank, so this made questing SUPER easy. I got thru 39 out of the 75? quests in Sholozar before I stopped. And, I stopped because I dinged 77, and could learn Cold Weather Flying. :)
So, there is a bonus from spending time past 68 in Outlands, at least on your first toon on the server. I only really spent about 1 level stuck on a ground mount in Northrend, before I could fly again. With only 2.5 levels to go to 80, I'll probably ding 80 before Pallormortis, who is currently 67 and doing Netherstorm quests, will need or want to start to start flying in Northrend, so I'll be able to provide the Bind on Account Book of Cold Weather Flying.
