AD ratios are for AD casters. And AD ratios is what actualy holds champ from scaling as an adc, look at Cait and Sivir. While they do want to give champion some ratios or else base value will have to be very high(Mundo) so they gave them AP ratios. And for the sake of these ratios being not completly pointless they made these ratios work to empover champs laning greatly. Sion, Yi and even Trynd are very strong laners with AP setup.
