I respectfully disagree. Being an avid doffer, I've got over 5k surplus fleet marks on my main toon. I don't really want people bringing attention to the CXP -> Marks missions, because I really don't want them nerfed as it's my fleets main source of marks.
I wouldn't mind doff missions that reward marks, but I honestly don't see it happening.
Since Heretic left, the DOff system has been shown no love - and I don't expect that to change any time soon. They didn't even add any new DOff missions when the new Rommie sector was released!
