Speed of bringing a weapon to bear, or making a successful strike, even hitting a target with a projectile weapon requires the proper positioning of the entire body, not just arm/hand speed. Greater strength allows the being to move faster while bearing more weight as well as striking harder. Balance and dexterity are also essential in scoring the hit as everything from foot positioning on determines the power, accuracy, speed and force of the attack. Skill with the weapon, or empty handed combat form add to these.
A player skilled with a rapier would not be able to apply those skills to a heavy sword, but one skilled with a heavy blade, understanding the differences between it and a rapier could utilize skills, such as thrust and parry quite well, their speed with the lighter weapon being much higher than with the heavy one, and the accuracy maintained. The same physics involved in the sword weights and lengths would apply to clubs.
A person skilled in the use of a ranged weapon with a short sighting radius will be even more effective with a long sight radius, assuming they have the strength to wield the weapon effectively, but the reverse does not follow.
Short edged weapons, or a short blunt objects, improve the effectiveness of hand to hand combat. A blow to the carotid artery with an open hand, or fist, it can be instantly disabling. The same strike with a dagger will cause the victim to bleed out quickly, but not instantly disable, depending on their commitment to killing you. Other targets on the opponent will provide similar results. Weight added to the blow can increase the impact severity, but at a reduction of the speed and accuracy, dependent on the strength of the player.
Hmm... perhaps commitment, tenacity and courage should be added. After all faint heart never won fair maiden. And luck, there is always the possibility of landing a lucky blow, or having your opponent trip on a shoe lace!
Summing this up; attack speed and accuracy should be based on speed, strength, dexterity, weapon and armor class. A player barely able to lift and balance a weapon is probably a dead player, regardless of his training with it or the awesomeness . Pretty much I agree with my understanding of what Prom, Kvetch and Toch have said.
Regarding the race choices, I also think a satyr is different fawn and might be cool, but there will always be a limited number of species in a world. If I remember correctly 4D has a race that is considered standard, gringos? Other races gain or lose attributes from these, but the majority of weapons, armor, etc. would reflect the design of the weapons and there would be races that would not be able to effectively utilize the equipment. A paw might be able to hold a weapon designed for a gringo hand, but not control it effectively. There should be an all supreme, super powerful, extra virile, extremely handsome, envied by all, totally awesome, undefeatable, viking race available only to Tor... and maybe a goldfish added. Make your choices from what is there.
Sorry, I didn't start out to write a book.
