I disagree. Obviously kat passive on any kit would be at least GOOD, but in order to have an effect similar to katarina, you need the kit to have mobility and burst. Leblanc, Talon, and Khazix are all contenders for this. Kat passive on karthus would be worthless because he's already got stupidly low cd spells, and the only thing you're really lowering the cd of is his ult,by 15 seconds each time. Good, but not "broken beyond belief". Also, most ADC's kits.
