Are there any Eye of the North quests we shouldn't finish?

Are there any Eye of the North quests we shouldn't finish, because keeping it active yields far better rewards than accepting the quest reward?

An example of what I'm talking about would be the Nightfall quest set "A Show of Force" and "Requiem for a Brain." These place a number of margonites and margonite bosses in the southwest corner of The Sulfurous Wastes. Repeating these quests over and over are can net you a few thousand LB points per hour, one of the best ways to grind for this title. Certianly keeping it active is far better than the pathetic 15 you would get for accepting the quest rewards.

So, are there any EOTN quests we should keep on our log?

Too early for that. Also if there are quests for farming people won't tell you now. They got to make their millions first.
