Fair dice was broken, at least a launch. If you had a really high armor class the NPCs would get an absurd number of nat 20s if that was the only way they could hit you.
One of the things I like from d&d 3.5 is the critical system, where an attacker who rolled a 20 makes a critical threat, but must roll again and hit to confirm the critical, so people with high AC don't get hit critically every time they are hit
