@Meddler Can we talk about AP itemization?

Specifically ap/armor. For AD mids, there's the super-powerful Maw, and AD mids aren't traditionally gated by mana, so they can rush it, and mercurial is an excellent buy too. With AP mids, there's zonyas, which requires you to sacrifice a lot of stat-power for the active. It seems like AP is drawing the short end of the stick, especially since AD mids have a lot more access to APen than ap mds have MPen. I don't want to belittle Zonya's power, but I just wanted to know what you're thoughts are on the balance between itemizing for AP vs AD.

Thank you for your time!
