Also remember that a +1 quality Chainmail only costs 4000-5000 silver (much less than standard plate) and it yelds the same protection as a plate for a -35% penalty. The rules specifically state that a Greater item is so common as to be llikely to be found already-made in shops.
I think adventurers will tend to wear superior specimens of lesser armors instead of the heaviest possible standard ones, once they level up. Note that even though the price is outrageous, it is possible to produce nonmagical armors that are the equivalent of RQ3 ones: 8pt plate, 7pt. chain, 5pt. ringmail and so on. A 5pt. ringmail costs 10250, headgear excluded, and is only -18% to skill, i.e. half the penalty of an equivalent chainmail. And although not available as a "pret-a-porter", it is definitely not rare.
In any case, I agree with Rurik that penalties should be lowered instead of dropped altogether.
