I just had a game with a full ap Nasus that ended 0/10.
He spent the whole game permapushing without making use of wards. he rushed a Banshee vs Ganplank and fed as much as he wished. When asked why he was doing that he just answered "i'm testing a fun build". When the game finished, he laughed at the rest of the team for having no damage dealt. But i guess it was just a bad game.
