Well i have a G12+3 GK with all defense sets, before the change he had 43% armor so each 20k hit on him did just 11400 dmg. Now he has 51% armor so the sets going from 5% to 25% added him like 8% armor runded down. So now instead of a 20k hit he will take 9800 dmg. So i earned like 1600 dmg resistance by the change. This is better when the dmg goes up. Instead of 50k he will only take 24,5k physical dmg. Thats 4k less then before the change. Those numbers are much better on higher armor characters.
