When I was doing the grind on my Trolls for all 5 factions/Argent exalted I did all except for the 2 jousting ones. Once you're exalted with all you can get like 4 more I believe that are very boxer friendly, adding up to about 7 that take 20 minutes or less.

If I'm really in the mood to make gold, then I go to the Horde airship and get the kill 20, slaves, assault by ground, neutralizing plague, drag/drop, kill Alumeth, then go to Shadow Hold. Get the 15 dragon kill quest (you can put all 5 toons on a separate harpoon and just spam "3"), burn the buildings (park 4 in the middle of the villiage and fly one toon around burning), go down to the little base on the cliff and kill the flyers and transform them at the same time, just park on the first tower you come to. That's about 1300g in probably another hour or less.
