1. Of course he'd be simple, much like Scorpion, but I feel he'll be the easiest to use and adjust to having multiple variations with, not necessarily just to play as. Because of how straight forward all of his stuff seems. Unlike Raiden, or Kano, or even Scorpion, who kind blur the lines or have one or two really specific-use and "out there" variations.
2. I've always been down with the Lin Kuei in general.
Subzero is the best of the main stay characters throughout MK in my opinion and i've always felt he'd make a better series protagonist than Liu Kang (and Raiden if you'd consider him that).
I didn't main him in MK9 because I didn't like the way he played, but as of now I get to choose how I want to use him and I'll be maining him in some fashion again.
He might not be number one for me in this game, but he'll be in my top characters for sure.
I'll just have to wait until I can get my hands on him.
