I still think you guys are using a typical fantasy mindset for how bows are really used. Strength is hardly merely a limiting factor (how strong of a bow you can use). It also determines how steady you will be able to pull the bowstring.
I guess it depends on how you define dexterity. In MO, dexterity seems to be a reflection of how nimble your hands and feet are. In a typical RPG game, Dexterity is often defined (incorrectly, imho) by what I would use the word "skill" for. Not merely a measure of how fleet and fluid one moves, but how precisely one does those things. Precision is a measure of skill, not dexterity. A guy can be smooth as silk and still suck ass with a bow. Granted, I agree that an oaf will probably suck with a bow, too. I'd take a well practiced oaf over a nimble greenhorn any day of the week, though. Of course, having more Dex will and should never hurt you...
I think, for game mechanics sake, archery should work as follows: Strength limits the draw weight of the bow, Dexterity effects the "downtime" between firings (for drawing arrows and knocking; as Talime suggested), Constitution/Strength effects how long the bow can be held and still remain accurate and Skill affects how "tight" the targeting reticule should be able to get.
Like I said in the first post, when you are talking about bows that can kill an armored man...Strength is more important than Dexterity. Remember, Dex is NOT how accurate you are. That is skill (character and/or player). Pulling the string:Strength. The speed and fluidity which you knock arrows
ex. Accuracy, timing, how you hold the bow, reference points used, ability to lead the target, stance and even how you hold the string:Skill. Not Dex. Even using the right muscles, as you suggest Flint, is not Dex. It is Skill. So I can't agree that Dex is more important than Strength.
