Semms like you got me wrong, I didn't want say that AD Kat is bad, her early game is actually pretty stromg with the passive damage, E and the AA resets and her midgame is pretty potent aswell. Early in the game building AD on her is better than building AP,  because of that level scaling on her passive, thats one of the major reasons why Gunblade was such a great first item for her in the past.

But midgame is also the time when AP Kat begins to scale and she is scaling harder than AD Kat, just because of the factor of penetration. Especially at a time when many ADC can get MR (even if it's not much) via Edge of Night, penetrations are important for Kat. And the enemy midlaner WILL buy MR aswell. That's why I usually buy Voidstaff as third or even second item. Also yes, midgame is the time to use the build up advantage and if you gain an early lead as AP Kat, you will keep scale until late game and grow stronger like snowball, pun intended.

Not to mention the item synergiez Kat has with certain AP items like Zonyas or even Rylais. The only good synergy Kat has with AD items is Edge of Night.

Again, I don't say AD Kat is trash, it has quite some potential if you are able to end the game quickly, but I see no reason to build AD over AP on her, because AP scales (and synergizes) slower but harder.
