TnA is probably the single reason Riot doesn't buff Katarina. If he were to get hit by a bus this week she'd have better ap and ad scaling, more range, the works, in next week's patch.

Anyway, he admits in several of his videos that he's team reliant to a great extent, and on top of that he's crazy at ward hopping. I caught him playing the other night and he ward hopped a Janna tornado that she fired [[from a bush]].

Kat is an assassin, the type that comes in once the initial cc burst is gone and easily takes out many important targets due to her passive. Picking the right moment to engage is very important. Also, she dominates many cc-less/ hard to hit cc lanes eg Veigar, Lux, Karthus and to some extent, Fizz.
