Renwood, now we're talking about a matter of degrees in how much random numbers are used. Myth uses them sparingly, it's true, but still uses them for things like damage amounts, arrows being slightly off target, duds, etc...
WoW uses random numbers more, it's also true. It uses them in the same way as Myth, and yes, if say someone swings a sword at you, you have a random chance to dodge it, another to parry it, if you have a shield, to block it, and there's a random chance they'll just miss anyway. The odds of these are modified by the abilities and gear you obtain for your character. But, it's also a combination of controls as well. Good players will move and position their character to avoid (or make) attacks. For example, if you're a rogue, you just don't click a backstab button and have the computer "roll" the results, you have to sneak up and move behind another player using mouse and keyboard controls before you can make the attack. Couple this with the fact that there are so many different attacks, defenses and counter attacks, and an old fart like me can't keep up with those who who still posses their fast reflexes and hand-eye coordination. I have to rely on wiser strategy.
In other words, there's enough action based combat to create a vast difference between really good players and really bad ones, same as in Myth. What Wow doesn't have that still bugs me is there's next to no friendly fire. For some reason, there are times when I really miss launching a big area of effect explosive attack against the enemy and having it hit my friends too.
