Reverse Missiles / not an "attack"

I should note here the post you were responding to was simply arguing for the returning missile to miss the attacker - I was the one who suggested there may be a chance for the arrow to pass through the Reverse Missiles (or possibly deflect into another target the attacker would like to hit). And it would be a chance, not a guarantee - I offhand suggested 1/6 just to make the rolling simple (roll 1d, penetrate on a 1, strike something else on a 2 or maybe 3, hit nothing of importance otherwise), but a full 3d roll could be used instead, perhaps needing a 3 or 4 to bypass, and a 5 or 6 to hit a different target.

For the case of Force Dome, I had thought there was an "Ignores target's DR" result on the Critical Hit Table, but apparently there isn't. With that in mind, it's probably inappropriate for there to be a chance to bypass Reverse Missiles - in a sense, Force Dome gives Infinite DR against everything, Missile Shield gives Infinite DR against Missiles Only, and Reverse Missiles upgrades Missile Shield's Infinite DR to have Reflective - but I'd still argue for the return missile to miss the attacker, so there's at least some benefit to having a Critical Success.
