For the mage update (Getting an "More AP = More Health") ( Yeah do we already have this?)

So i read all the conversations about the new mage update and all the comments about "Mages are squishy and diana kills you instantly with Q+R" so i thought of an item like this, "More AP = More HP" Think of it like tear (Not really, i mean you stack AP or something) What i mean is that Gives you %AP the more mana you have and maybe this will work with Health instead or something, And the mana regain thingy yeah you lose mana fast with a lot of champions like (Yes hes not a mage, Wait he can go full AP can he) So Riot can you add Mana regain/AP items (good ones) plz?

Yeah i sound a little disappointed and angry but really Im not, i just want League to be balanced AF

bye
