Rotating the base set goes completely against the reason for having a base set.
Basic cards are the sucky cards everyone gets for free. You're not supposed to have to buy them. They are not supposed to be great cards. You are meant to feel good about growing out of them as you get better cards.
That's why it's OK if they get nerfed into oblivion. If you are using certain Basic cards in every deck, there's a good chance they are too powerful to be Basic cards.
It's true that there are still some Basic cards that are quite powerful, but power level isn't the same as ubiquity. If you take a close look at all the archetypes, you'll find that surprisingly few Basic cards are autoincludes in every single deck.
