How does that make it any better? No damage on a 20 save is completely unrelated to the fact that a high level fighter is heavily penalized by fumbles on a 1 while their wizard buddy likely never has to worry about it.Except if you also houserule that a nat 20 in a save is no damage at all, as my GM does.
Even back in the day when we didn't have multiple attacks it didn't make sense since the "penalty" for an archer rolling a 1 was to hit that fighter that was in the front line.
