I prefer self-contained rules, yes. I also know there are people who prefer otherwise, and that's why I said "another way to look at it" and not "the right way to look at it"
As I have already stated, my ideal situation is one book with all the rules (which is the way my favorite games work: Call of Cthulhu, Pathfinder and Rules Cyclopedia D&D). Not having that, I'd choose the "small packages" model (as D&D 3.x) over the "everything intertwines" of 4e.
Please note the "I". I'm aware that there are other ways and that they seem to be pretty successful, even more than the ones I prefer. Luckily, we all can have what we want.
