Max w, apparently the "new meta" for katarina is too build tanky too. The ideal situation for katarina is if you have a competent and you q e w then ult. You are supposed to e as far into their team as you can then while they focus you your team will then rip them apart and u get ur cd's refreshed once one of them goes down and you rinse and repeat.
Gt-fullmetal9yanal I hate most of you. This has been entrusted to me. http://i259.photobucket.com/albums/hh291/sly_reflex/trollomen.png
Wait for the enemy team to blow their cc's and get low. Leap to squishiest target you can leap, blow combo. After one of them dies, spam Q>E>W until you run out of targets or cannot skill reset anymore.
The important part is paying attention to who has burned their cc. If you dive right in while hard cc like Ali's Pulv, Blit'z ult, etc. are still off CD, you're gonna have a bad time.
