I'm sure many of you are familiar with the Quest Jack Me Some Lumber for the argent crusade. You chop down some trees and then an add appears that you agro for each tree you chop down.
The exploit is, you can avoid the adds after you chop down the tree. Just spam flight form right as you're finishing chopping, and you can fly away and go to the next tree without any agro/time wasted.
I did a search, and didnt find anything posted already. There were a few posts on getting extra wood to save up for future dailies. Combining those 2 exploits with epic flight form = free instant dailies every day for a long time.
