You know whats funny?

So I just played a game where this person, lets say Tim, picked kat and got lucky in one for all. We played against nasus (nasi? idk), who built mr. Tim said, "guys lets build ad, we can win" and he doesn't build ad. The funny part is I read all of kats abilities and they said. Kat throws a dagger that deals set damage + (ap ratio) + (ad ratio) MAGIC damage. For almost every ability after the damage dealt, it says magic damage.
