If you mean well written vs beginner books then I don't see that happening. At least not anytime soon for reasons already stated above. If this is what you mean then if you want to have at least a somewhat more accurate chance of picking out a good one by checking out the ranking for originals. (somewhat)
If you mean between signed originals and unsigned then I'm inclined to agree. Though right now I'd very much prefer to get a separation between original novels and fan-fiction types. Also a different type of powerstone that can be used for originals and another type for translated ones.
