WOW Gold: Start with the easy ones that are grouped together in the game
Level 63: Still do a bit of KQ, but if it’s taking WOW Gold a while, do some quests. Start with the easy ones that are grouped together.
In other words: Pick a map you have quests in, and do only those until you level. Grouping the quests together like this means less walking from map to map, and more exp-making.
Level 64: Save the bats quest (Big Bright Golden Bat Tail Hair). I mean it. Save it. Do the other quests, but keep the dungeon one still. You might have to grind in abyss for part of this level (I did for 10%), but it should go pretty smooth again, if you level and still have other quests besides Bat and Dungeon, save them for 67.
Level 65: You now have Dreadful Elf in the Forest 2, asking for 120 Greenkies and 30 Greenky Big to be killed. Spam it. Save all other quests.
Level 66: Same as 65.
Level 67: Do all of your 65, 66, and 67 quests, you should level. If not, spam out KQ for the remaining exp.
Level 68: You now have Hair Remover, calling for you to kill 70 Lizardmen and obtain 20 Muds. Save all other quests.
