Okay, I guess it's a question of design choice. I was imagining that an inflation of to hit cards draws and their corresponding sva draws could become a little cumbersome ( charging with a lance on a unit's flank would require drawing 6 to-hit cards and their saves)
More generally, I must say I have always been very skeptic about the appropriateness of the wild destructiveness of many miniature games, and the corresponding "empty battlefield" syndrome, specially for those in the "fact-paced" category. For sure, players often associate "bloody" with "fun", although I personally fail to see a direct link between both.
But in fact, the battles themselves were rarely bloody (with a few spectacular exceptions) in terms of % of casualties. The slaugther generally occured after one side broke and ran, with winner/loser casualties ratio going from 1/10 to insane 1/50 or more on some occasions. But that happens after the end of the game! Battles where one (or both) side(s) would lose a third or even half of its physical mass, and therefore ability to over ground, while retaining some ability to fight ( which is what happens in may miniature games) never happened in reality.
Anyway, just a point of view...
