No, it doesn't.
Please remember, origin-oriented mission content is just one suggestion.
It is a suggestion that involves quintupling the workload for all new content generated under the paradigm, made by people who do not expect to have to do any of that work. Your excuses do not change the work required nor do they broaden the audience for it. Either you plan to do the work yourself or your suggestion is bad.
Are you the one that would be doing said work?
How do you know it would cause 5x the work anyways?
The Secret World (original not legends) had three versions of all the faction arcs -- some story different view point. Same Assets, Same Location -- doesnt have to take 5x or even 3x the work.
