Deedlet has officially completed the Hellfire Peninsula portion of Jame's leveling guide! As I went, I made a few revisions to the guide, but all were superficial - adding more arrows (to flight paths, for instance), breaking large steps into smaller ones to make things smoother.
Next stop, Zangarmarsh!
Also, I'm about half-way through the Barrens Guide with Mokrana, so an update on the speed testing will come soon. Unfortunately I'm not to happy with the results so far, but you'll have to wait for the details on that.
