| First off, Matt's post is dated 3-26-2006. So it's out of date, they fixed that since than. However you can do this.
You get your Field Duty quest, prepare your papers, go down and start the event next to Hive'Zora (alliance btw). Have your full mount gear on and ready to go, boots/gloves/carrot. After the event, captain needs to stay alive. (I was a priest so doing this was easy) Memorize where he runs back to after the event, stand close to it when the mob is almost dead. As soon as he is dead, start mounting up.
The captain will run back and you can talk to him while mounting as well. Get him to sign your papers and start mounting back to CH. Go straight and fast as you can to the turn-in. Select some kind of assignment, I usually did Tactical (I'll explain later). Start your Field Duty quest again. Preparing your papers should almost be done with the cooldown. It's important to prepare them as soon as you can. As soon as you have Field Duty, start mounting back to Hive'Zora.
Once you get there, get off your mount and prepare your papers. I had my papers hotkeyed lol. I usually prepared them as i jumped over the tents, and got off my mount in midair. Land, talk to the captain, and get him to sign your papers again.
Wait til he disappears, and start the event. Now go back, turn it in and get the quest again, repeat. IMPORTANT -> Prepare your papers as soon as the cooldown is up.
Advanced trick, don't start the event after the 2nd turnin, go back and turn in the quest and pick tactical. Head back to start the event (prepare papers as soon as u can). Now if you have one of the tactical quest for the Hive'Zora scout (I have done the other scouts a couple times and made it back okay) You can go and run to the scout and get back before the captain is dead, heal him up and be good :}. Turn in the tactical quest to the turnin NPC after the 2nd field duty turn-in run back.
Each field duty turn-in is 25rep. Tactical assignment is 50rep. So you should be getting 50rep a mob kill and sometimes 100rep.  |
