Well, I was just pointing out that str is already unballancing the game as it is, determing both damage and accuracy as well as the permitted gear carried. By the existing rules, strong fellows are always more accurate than their even leveled weaker counterparts. Wielding a simple not-too-heavy weapon like a dagger or longsword this is just lame. Controling your blows by not using all of your strength is very difficult and shouldn´t add to the chance to hit, quite the opposite, actually.
But hey... it seems that there are differing oppinions on this subject so maybe it´s not such a terrible rule after all. My gaming group has just always thought so, and we feel that it added to the balance of the game when we shifted the modifier to dex. Each to his own! Do whatever feels good for you!
