since most AP champs rely almost entirely on abilities, MR is more effective at lower amounts than armor is against AD carries. This is b/c ad carries have sustained dps and deal larger amounts of damage over a larger time frame. Since AP carries must wait for their cooldowns, their damage per second is more limited than adc over prolonged fights.
