I'm lousy at math.  See below.)A miss chance is more valuable to a low AC than to a high AC.For example, consider ACs of 15 and 25 versus an attack bonus of +9.Against the 15 AC, the attacker hits 75 percent of the time.  Add in a 20 percent miss chance, and the attacker's overall percentage to hit the 15 AC becomes 60 percent (75 percent potential hits, less one-fifth that become misses).  That equates to an AC bonus of +3.Against the 25 AC, the attacker hits 25 percent of the time.  Add in a 20 percent miss chance, and the attacker's overall percentage to hit the 25 AC becomes 20 percent (25 percent, less one-fifth).  That equates to an AC bonus of only +1.I quite like the interaction of miss chance and AC, so I wouldn't be up for simplifying.  Just have the attacker rolls another d20 along with the attack roll ... since miss chances are in 5 percent increments, that should be easy and quick enough.</blockquote>
