I think, as an alternative, there should be a fairly involved, long quest line ...
......I think we have an opportunity here to make use of multiple zones that are completely unused atm. Using zones like Kael, Wakening Lands, Burning Woods, Chardok, Beholder, etc etc.
My goal with the design would be: For a single person/new player trying to get Fighters/Casters guild flagged, they would run through the long quest farming mobs all over the world with very little chance of things being camped (multiple people could be killing the same type of mobs, everyone has a chance still). Players looking to quickly finish the quest via purchasing items can use the old way.......
I like this idea. Would really like to see more utilization of the other zones. Make the items no drop as well! Pardon me Kejek for paraphrasing your post.
