I assume that Star Wars d20 has energy weapons that do large amounts of damage? That makes a big difference as regards armor-as-damage-resistance, since a dagger doing d4 damage quickly becomes useless.
IMO having armor use damage resistance really encourages the use of greatswords and greataxes over all else. You end up with less variety in weapon choice.
