make natural souces of pv unpenetrable
one of my pet peeves is getting my armor penetrated. i understand its necessary to even the playing field in the late game, but i find it odd that you receive full damage when it occurs even with a toughness of 50 and tough skin talents. i feel it would make much more sense that when a monster punches through your armor there should be a last line of defense; your body.
what im proposing is to separate the sources of pv for game mechanics purposes in much the same way it is done with dv so that for instance a fighters pv bonus from his class power counts as natural pv in addition to tough skin talents and pv bonus from toughness. so even with a penetrating hit you wont lose 100hp for instance, just 75.
i feel that this would do a few things, 1. it would make fighters class powers relevant in that you would receive 15% invincible pv instead of just more of the same. 2. it would stop some cases of instant death ( "the doppelganger king punches through your armor and critical hits you" yes this happened to me a long while back) 3. it wouldnt be too overpowered, because its very difficult to improve your natural pv.
