I've been having what is apparently a scaling issue caused by inflated secondary stats on some Wrath of the Lich King items. In particular, my Highmountain tauren warrior leveled through Northrend and picked up a green, iLvl 87, 2h sword. All of the secondaries were in the +25 to +30 range, and the Dugi Gear Advisor decided it was better than the heirloom 2h axe I was using. So I went ahead and equipped the sword.
Affliction: Endless Affliction - Your Unstable Affliction deals the same damage as normal, but its duration is increased by 6 sec. Demonology: Nether Ward - Surrounds the caster with a shield that lasts 3 sec, reflecting all harmful spells cast on you. Destruction: Demon Armor - Protects the caster, increasing maximum health by 10% and increases armor by 150%. Warrior
No he's just not paying attention. The wanted quests are built into both the leveling guides and the "Zandalar Forever" achievement guide. They aren't in the rep guide because they are not repeatable and by the time you hit max level they should be done. You'll also notice the rep guide doesn't contain every single possible completable quest that rewards rep. It is designed to focus on repeatable objectives, world quests, large quest lines, and missions.
