You imply that in DoS each play through may NOT yield a different result, and that is simply not true - I played DoS games (1&2) for over 1000h, and replayed combats were different and interesting each time. And randomness in DoS is so small that it can be ignored.
Also, my suggestion would require very limited "use of resources", and if that would prevent alienating significant fraction of user base ( those like me who are annoyed at frequent misses/low hits ), then any manager would tell you that it IS wise to do it, especially if it would be non-default option. Key question here is if there is really "significant fraction" of potential users that are annoyed by randomness/misses - and admittedly I have subjective opinion on that question.
