The thing is, standard warstories are easier to criticize precisely because they follow some guidelines. If you want, you can relate them to a realistic painting (of any period), where technique --in playing and writing, in the warstory's case --is easily observed. This story here would be more like an impressionistic painting, or perhaps something even more radical. It focuses on giving us a good experience through reading, and at the same time, the author makes his point clear: sometimes you have to think outside of the box to win, even if it means shooting yourself in the foot.
I still like "traditional" warstories a lot, but these show a fun and different way of doing things.
