Kat Observation (BALANCE ISSUE)
It used to be; A good Katarina could beat a decent Orianna in a manner of skill - even though Orianna is a pretty good counter.
now
a bad Orianna can beat a good Katarina, in a matter of mages being the new assassins. Ori can combo kill + auto attack a katarina to death before any kind of (passive) dagger play can happen. Throw a dagger in the air for move speed, and yep youre dead before it lands.
Sad but true.
