Would not a better solution be to return to a tbc style model? One were the game outside of raiding focused on the world and dungeons to a greater degree? For the sake of argument let's say you are right (you well could be) and time played and percentage played influenced how many resources content would be given.
Why not work around that then? Stripe down raids most of them really dont need more then a series of rooms and a scaled up mob to be a boss. Think gruuls lair it had everything a raid needed. Take the slavaged budget and invest it into dungeons. I dislike the weird argument that the entire game need to be polaxed to allow lfr its survival. To be clear from what I commonly see it is a near consensus that lfr lives not from its content but from its rewards...
It might be time to have a bit of faith in the game and take a long look at how it is currently structured. If content only stands on its feet from a skinner box style reward system I would dare say it needs to be reworked.
