I totally enjoyed the one southwest of Warsong Hold. it was one of those that i would not want to box.
after gathering parts to make the tanks work, you get to ride one into scourge areas and kill them. well i did that one over and over and over and over. turn in quest but couldnt repeat it. this is when dual boxers get a secon try to bomb scourge to their hearts content. after about 20 minutes of driving in circles gathering mobs, pressing the landmines button, and returning to get a new tank after the current one took too much of a beating, i got my fix and turned in the quest. i guess some vehicle quests are better than others and are worth doing 2, 3, 4 or 30 times.
