While reworking Katarina, can we do something about her damage types for clarity?

As a new player it really confused me that she dealt magic damage.

I mean the first few games against her I build armor, because like she is stabbing me with blade, obviously duh... NOPE.

Bouncing blades second activation (consuming a mark) is the only effecty that sounds like it should be dealing magic damage. All the others are versions of stabbing with a knife.

btw I realise that would impact her item build, but personnaly I see nothing wrong with full AP + Black Cleaver for example (;
