Shadowmoon Valley 69 - 70
Once in Shadowmoon Valley head to Shadowmoon Village(1). Grab all of the quests and set your hearth here. Now head right out of town and assist the Shadowmoon Scouts in killing 10 Infernal Attackers. Once you kill 10 of them continue south to (2). Here you need to kill Diemetradon's For 8 Felfire Spleens and collect 15 Everburning Ash. When you're done head around (3) and kill 20 of the Shadowmoon Wildlife, Aka Boars and Chimeras.
When you're done head to the Altar of Damnation(4) and refresh your quest. Now head south to (5) and kill 8 Enraged Earth Spirits with the Spirit Calling Totem down. Once all 8 are dead head east to (6) and kill 8 Enraged Fire Spirits with the totem down as well. When you're done return to the Altar of Damnation and refresh your quest. Now head northwest to the Sketh'lon Wreakage(7).
Here you need to kill the Arakkoa for Sketh'lon Commanders Journal Page 1, Page 2 and Page 3. Once you have all 3 Pages return to Town and refresh your supply of quests. Now Equip the Spectracles in town and kill 12 Shadowmoon Zealots. Once you're done refresh your quests and head into Legion Hold(8). Head up to the top and use your Box o' Tricks right next to the Legion's Transponder thing(9). Watch the Short Scene then jump down and kill Overseer Ripsaw. Loot his Start a quest item then return to town and refresh your quests.
Head back to Legion Hold and grab the Fel Reaver Armor Plate(10) and the Fel Reaver Power Core(11). Also if you're able to solo elites kill Morgoran for his Glaive and Makazradon For his Glaive aswell. Morgroran is around 24,40 and Makazradon wonders around the lower portion of the camp. Once you're done both quests return to town and refresh your quest. Now return to the Legion Hold for the final time and head up to the Green Glyph(23,39). Use the Fel Bomb to destroy all the infernals. Once they're all destroyed head back to town and refresh your quest.
From town head to Scout Zagren(12) at Slag Watch. Refresh your quest at him then head a tad east to the Deathforge(13). Here you have to kill 10 Guardians and 5 Summoners. When you're done return to Scout Zagran and refresh your quest. Now head along the path and find Parshah(14). Refresh your quest at him then head North to the Sketh'lon Wreakage and kill Asghar(15) for the Sketh'lon War Totem. Once you have that return to Parshah and refresh your quest. Head northeast afterwords to (16) and kill 5 Enraged Water Spirits with the totem down.
Now what i'd reccomend doing is grinding as much XP as you can to get you around 200-500 from level, and turn in your quest to hit 70. If you do this, it will allow you to be above others in level come Wrath of the Lich King.
And...
Congratulations on 70!
