I my opinion your analogy is off.A useless rant over SP > MP i see. And your analogy is completely wrong, it goes more like:
Asking a 5 star cook to prepare food for a farmer. A farmer has a solid knowledge of the basic ingredients such as a potato, carrot,... and all sort of other crafts (In this analogy the "basic ingredients" are the SP people who know the basics about the combat)
But it is the cook who will create an astonishing meal for both the farmer and the cook (Here the cook being a MP player who is dedicated to playing the combat)
A meal made by the farmer will be good enough, but the cook will be utterly disgusted by the meal the farmer made. Why are you trying to make a bad meal when you can have an astonishing meal for both the cook and the farmer?
Asking MP guys to improve overall quality is like designing a whole car around its tires, just because they're vital to the grip, speed, etc.
While the tires may give some constraints, it's not good design choice to do so.
Going back to food, it's like trying to feed construction workers with 5-star chef food (i.e. small quantities, exquisite flavors). They need meat and potatoes.
