you know, i don't get why everyone thinks this works best against high armors,when mathematically it does more to low armors =_= say your enemy's armor is 500 to start, reducing your damage to 1/6 the original. After armor reduction the damage is only reduced to 5/27 the original. your damage was increased by 11.11 repeating % with the 60 armor reduction. Say your enemy's armor is 200 to start with, reducing your damage to 1/3. After armor penetration the damage is only reduced to 5/12, resulting in a damage increase of 25%. As you can see, armor penetration has a greater effect on lower armor people than higher armor people, where it's actually more useful to just buy a crit chance or attack speed of +15% when your enemies have an armor of 500.
