Both.
Kano's knife toss controls the pace of the match against most characters. Unlike previous zoning characters like Freddy and Zod, Kano is also very good at mid range. He has Sinestro's b+1, Sub Zero's d+4, and move that can hop over low attacks when timed correctly. Every normal attack is safe on block too and provides very good hit advantage.
A safe armor move is rare in this game, so you cannot hold that against the character. Lack of a 50/50 mix up is an issue when you are down in life.
I know I promised I would behave myself in Mortal Kombat X, but if Kano gets normalized and all these 50/50 mix up characters remain the same, I am throwing a tantrum that will make the "The Great Scorpion Scare" seem like an everyday m2dave complaint.
