altho i agree with the concept, i'd bet that Iztvan's request is nowhere near being easy. every new variable you add to the equation makes it that much more difficult to calculate. Currently, you simply have speed > 1 and opponent speed = 1 to contend with. your request would also have to take in effect terrain and unit type, then calculate all the variations of all 4 factors. Which factor takes priority? Take a simple example, a guerilla attacks a cavalry in the the woods (1m vs 3m), who gets the retreat option? Maybe both should get it, depending on who gets to 1hp first. Maybe they cancel each other out and neither can. But just imagine the arguing that would result, based on those few times a spearman beats a tank, I can see this being a much bigger debate.
