The reasoning is this: AD carries have strong AD-scaling abilities/something else that encourages building AD. There is no viability in building Cho or Skarner as AD. Their high base AD gives them more damage, encourages Sheen/Trinity Force, and does not make them terribly overpowered, since they don't have an ability that scales off AD in the way that a carry like Ashe would.
