Why dont you get right on that, ok
It is not like you have to buy the book, and D&D combat works fine as it is. To bash an optional combat rules supplement for adding an xtra layer of complexity is silly. It is an optional rules supplement meant to be overlayed onto the existing game, of course it is adding an extra layer of complexity.
You basically just said you do not like chocolate, and thus you will not like this new chocolate cake and should be eating vanillia pudding instead.
You are right 100%, if you do not like chocolate dont eat chocolate. but do not disparage a product, because it is clearly, and obviously spelled out to be chocolate
(The point is somewhat serious, but no harshness is intended, thus smiley faces, chocolate, and pudding refrences)
