@Kosh: Ok... that'd sort that matter out fine then. @Hydro: You're right... it would add up fast. Along the same lines, I think I mentioned earlier that we need some adjustments to Defense. Currently, no defense modifiers matter at all after 'high explosive' units hit the field. Therefore, right now, Arcology Shielding, as an example, has no effect whatsoever. We need some additional depth to some tags on Defense to compensate for this. And that's something we should be thinking of now with these as they subtract defense... currently, the penalty would only apply for non-high-explosive and after units, thus only early units would benefit attacking a city with a -defense penalty.
