Yo, Been a while since I posted anything, better late than never. This is a new vehicle grind spot. I got really tired leveling my rogue and went to do the prequests for the quest No fly Zone, which works the exact same way, except it's 9 quests away from this one. Props to Captain Bad, for this topic which got me goin. Do all the prequests until you can start The art of Being a water Terror. Get the quest, jump into your Water Terror and just destroy everything. I got to 570k exp/hour with breaks until I went offline.
