Maw armor pen needs to go

Riot i don't see the point in why Maw needs armor pen, assassins have so many item choices to shred armor with and you give them another one which they will build. mid laners don't have much armor choices without actually benefiting power wise. they get hp yeah but that's it really, zed yas talon kha and rengar all will build maw against ap champions and i think it's excessive how much armor penetration AD champions can get.

these are what assassins and other ads can build these are choice which i would see a mage building and benefiting from armor
