Kitana is usually very easy. I think out of all the matches i played against kitana, i only got beat like 3 times out of 50 using my NW. Just me though.
Probably because his spear is Alot faster than Scorps or Humans Smokes. Also, His tele-uppercut catches alot of people off guard. And You get caught twice and your done with his easy 40+% combos.
Basically, people dont know how to counter him, and they consider him noobish. Alot of begginers do.
