Defend the Rebel Camp

The best idea I saw, worked for me fighting alone (dk). Clear the road up to the questgiver, then take the quest and move back down a ways to the outside edge. You should see an occasional troll come down the hill and run into the fight. If he doesn't attack you and goes into the fray, you're at the right spot.

An occasional troll will come up the road from behind (shoots a single arrow first), but kill it and you should even have enough time to eat or heal before the next one trots up from downhill. I probably could have done it without healing and I'm dps geared.

I made the whole 3 minutes with ease.

1) Accept quest while on flying mount (best to do this when nothing is attacking the quest giver)

2) Fly straight up as high as you damn well want to go. Straight up, do not move left / right / etc. I did not fail the quest for flying super high directly over the quest-giver.

3) Wait 3 minutes.

4) Turn in quest and profit.

As of 6.0 the NPC's at the camp are level 100. You don't have to lift a finger and the quest will complete itself.
