Another Armor AP item PLEASE???????

Am I the only one who thinks mages need more itemization against AD assassins??? Currently there's only ONE AP item that also offers Armor, Zhonya's Hourglass ... And I also find it very strange how one of Zhonya's components is only used for this one item, Seeker's Armguard . That item in particular has a LOT of potential to give more AP Armor items, I mean just look at it! It already has AP and Armor and already is a component to be used in other item recipes. (IMO) I personally feel it's very much needed because the little bit of armor gained from Zhonya's isn't nearly enough against midlane assassins (cough Zed cough) and with the incoming changes (nerfs) to AP items in general, another option for armor would benefit mages IMMENSELY.
