Having a reliable counter to Nasus top that doesn't stagnate the game, pushes quickly, helps his team out afterwards rather than having to babysit top for ages, and is still capable of being remedied by actual teamwork on the enemy's part due to the inherent danger Mord's place themselves in.
Good night, sweet prince. May flights of angels sing thee to thy rest.
