Finally someone who thinks with his head. I actually did this myself and found out the same thing bug I restrained myself from posting it here because of people like 89.75.58.109 and others who will do everything to prove me wrong.

Ok for the gods sake who can get 400? Only a select few champions could get 400 armor and the second thing, who will even bother to get 400 armor? 250 is quite enought for a tank, going beyong that is just wasting money.

Also if you took a calculator in hands you would get that 400 armor target will lose 140 armor from last whisper and let's say 50 armor penetration from items and runes will yield 190 armor reduction leaving the target with 210 armor.

Now in the season 2 the target would first go through 50 armor loss which will be 350 armor and 40% armor penetration from last whisper (last whisper had 40% not 35% like now) will be 140. So in the end armor reduction is 190.

This not only proves that armor reduction is not that almighty as it is stated but it proves that RIOT knows what are they doing. Don't think they thought of everything.
