cough teams with a fuck ton of cc and you want qss? Bad idea im guessing? I actually checked it out in the training mode and AD kat deals about 300 less damage with her overall combo than ap. So it isnt HORRIBLE. I believe the total for AP was 3400 and ad was 3100
this is what i had built 
Eternal Torment3 votesyou can just take cleanse on her. ive seen many flash-cleanse Katarinas walk around tbh and they always did remarkable
Rengooo1 votesNot seriously no.... But I have played full crit Kat in a few featured game modes just for a laugh, and once you have a few items you can deal some serious damage - you auto very shortly after using E to dash to someone, so a crit plus say Ravenous Hydra active can not far off one shot a lot of squishier targets.
