I like the stats how they are now. Not everything gets better by making it more complex and confusing. In most situations in life (even in RPGs) the simple solutions are the best ones. If people have to read manuals and things like that for half an hour before the can even play the game, there are some serious flaws in the mechanics. These mechanics were ok for the old D&D games because the rules were in the background and many people already knew them but for a new game you should make the systems so complicated. Just make them meaningful. Every stat should have a real impact on gameplay, that's the most important thing imo.
