Level 80 at last. Salty Atoz the Explorer hit the cap in Zul'Drak, shortly after beginning to quest there. The route I took from 70 to 80 was like this: Borean Tundra to Howling Fjord to Dragonblight to Grizzly Hills to Zul'Drak, doing every quest that applied to the zone questing acheivement for Loremaster. This leaves the rest of ZD, Sholazar Basin and the Storm Peaks as pure profit via questing. In addition to that, it's time to grind some rep, level Tailoring, Enchanting, First Aid and Cooking the rest of the way to 450 and do a million other things I couldn't do (both in game and IRL) while obsessing over getting to this level. Wrath of the Lich King FTW!
