OK, if you are looking for the fastest way to make 100+ gold with the newest quests in the game as of 2.4, don't bounce around. Head to the Isle of Quel'Danas and pick up the quests for on the island only. Start on the Greengill coast, and do the 3 quests there, move to the demons, then to the dawnblade, doing the ley lines as you go. Then go do the quests to Convert the malfunctioning arcane protectors and recharge the crystals ending with the bombing run and Keep the Enemy at Bay. Takes approximately an hour and a half for a Prot Paladin and about an hour for a Destruction Warlock to do and nets between 100 and 150 gold.
