In general, you can not have "too many" stats for realism. Intelligence alone could be broken up into at least a dozen stats, and sword-fighting involves at least three kinds of Strength (swinging fast, shoving someone backward, and swinging repeatedly without tiring). I once sat down and wrote down what I thought would be every meaningful attribute/ability score for an action game. I narrowed it down to, I believe, 45 attributes that were distinct and useful enough to define. I still have it somewhere, and use it as my "bible." When I actually sit down to design a game, though, the final number is always between four and twelve.
Why? Playability, first. And second, because in different genres, various abilities are considered as one. Or aren't important.
