Fly to Zul'Drak, accept the daily quest Troll Patrol - Quest - World of Warcraft
and then go east, accept Troll Patrol: Intestinal Fortitude - Quest - World of Warcraft.
It's now the fun begins.
Do Troll Patrol: Intestinal Fortitude - Quest - World of Warcraft and then turn it in, abandon Troll Patrol - Quest - World of Warcraft and accept it again.
Rinse and repeat. ONLY do Intestinal Fortitude and you'll get 250 rep every time you hand it in.
The bug: All the other ones give 25/75 rep each, Intestinal Fortitude gives 250.
Doing it 25 times (It counts as a daily) gives 6250 rep and if you have epic flying mount 1 run takes about 2.5 minutes. That is 6250 rep an hour.
What we just discovered (while doing it) is that if you relog after you have done it 25 times, your 25/25 dailys will reset!
We both have done this 1 time each and it seems as every time we did Intestinal Fortitude it counted as 1 daily, but as you relog the 25/25 resets and you can do them again! (Other dailys do not reset, only this one.)
So, with this, you can become exalted in just a few hours of mindless shouting at cowardly soldiers!
A picture where to accept the quests and up in the left corner is when I had repeated Intestinal Fortitude 5 times, then the picture to the right of it is when I had relogged.
[PS]
the quest giver hands out different dailys on different days. So this is only possible when the daily is " Troll Patrol: Intestinal Fortitude".
