The dugi levelling guide for Dragonblight 73-76 needs a lot of work. It runs off the rails at Wintergarde Keep. Quests no longer offered as in guide. Different quests that are not in guide, etc. etc.
The guide was okay step for step until "Leave Nothing to Chance". From there until "Understanding the Scourge War Machine" inclusive needs fixing. Then it completely runs off the rails again at "Into Hostile Territory". Most quests as listed cannot be completed all the way to "Plunderbeard's Journal" inclusive.
