There was a video of some "pro" explain why Kang is so OP. He said that you litteraly need 10 minutes in the lab with the character and you are ready to go, and can beat players way above your level. He even said this is true even at Pro ranks, which mean a player that is obviously a lot lower level can up for that with the character and levels things up.
As far as Jade goes, she really isnt anything special at pro ranks. SonicFox give her a try, and lost 10-1 to ninja Kang with her.
Jade is so call "zoning character", yet Sonic could not do a s**** against Kang. Has is that fair?
The moment you are trying to use Dodging Shadows Flying Dragon Kick will wipe your **** in the face.
But still SonicFox said he will continue to use her, so he obviously see something in her.
SonicFox also said Johnny Cage is the man to counter Liu Kang, what you guy think ?
I think high damage character have bigger chance against Kang, compare to character like Jade or Dvorah with small damage and you need to open him like 10 times, which you will need to totally outplay him in order to beat him.
I think Baraka is one of the characters that have good chances against Kang.
