Offensive masteries give 10% arpen.
Crystal Scar gives 12% arpen.
Last Whisper gives 40% arpen.

Before flat arpen, with one item, you negate 62% of armor.

I'm not saying OP, I just added the numbers and it seemed awfully high.

Discuss.

Your numbers are wrong.

10% x 12% x 40% = 52%

It is not "before flat arpen". It is after flat arpen.

On a different note....MR per level for tanky supports next update. OP?

Why don't you read up on damage mechanics before making threads like these?

In theory it sounds like a ton. But in reality, it's necessary.


Tank builds are insanely popular on Dominion. Almost all of the most popular champs are those that do great damage while building nearly entirely tank, like Kassadin, Warwick, Urgot, Wukong, Yorick, Poppy, Pantheon, Udyr, Lee Sin, etc.

If that armor pen wouldn't exist, you could probably axe off almost the entire carry roster.
