True damage

Why does riot have such a fetish for true damage on certain champions? For instance Vayne. Don't get me wrong it's nice to be able to play an adc and not have to change your build to counter a tank, but this is just too much. She as well as basically all adc's with infinity edge never have to build any armour pen to stop a tank. Even a fed one. In my opinion a tank that is building specifically to counter an adc should require that adc to build armour penetration or something that will hinder them from their preferred build. At the moment anyone who builds with true damage like Darius or Irelia or adc's should have to change their build at least a little bit to stop a tank.
