Magic pen is not only not useless against him, it's more effective against him than any other melee, as he has the lowest base MR of any melee champion.

His passive shouldn't really affect how you build, because it's going to mitigate 15% of your damage no matter what. Unless of course you can do physical damage like akali or something.
