Or saying that a super coordinated rogue [edit]wouldn't[edit] be good with a broadsword.
Yes because in this case the rogue is only super coordinated when it comes to using bows of some kind. Strength, Dexterity, and Intelligence could always be renamed to Fighting, Archery, and Magic if it made you feel better.
This does limit the ability of those attributes to be applied to other situations, though. You wouldn't say that a rogue was able to use his archery to pick a lock, or that a warrior's fighting could be used to carry more weight.
There's a reason terms like "strength" or "dexterity" keep coming up in these types of discussions. People aren't just thinking of some sort of abstract quantity of "warriorishness" or "roguishness", they're imagining a warrior as being strong and a rogue as being dexterous, respectively. Those are the qualities that a lot of people associate with those professions.
Every concept in a game isn't completely abstract and arbitrarily defined. You can't just say "call these quantities whatever you want", because the names we give them have an entrenched meaning that makes them understandable and familiar.
Anyway, I don't think it would be terrible if you gave +1 to damage with all melee weapons per 2 points of dexerity, so that even if a PC wasn't very strong, being agile was still somewhat of an advantage. Although it still wouldn't be as effective as brute force, in this case. Bows might also have strength requirements, since draw weights could be very high, as far as I know. I admit my knowledge about medieval weapons is very limited, though, so I could be wrong.
Anyway, Aukustus, I do think you've got some really solid ideas, I was just curious what you thought about my question.
