Raiden has been my main guy since MK1 in the arcade. I'm really amazed to see how he looks in MK11.
I also like Kung Lao, but I didn't feel comfortable with his combos or special moves. One weird nitpick is I liked his Buzzsaw Variation but not the modified hat, it looked weird. That is another reason I'm looking forward to all the customi variations in MK11.
I'm also a fan of Sektor, but I wonder if the cyborgs are coming back. Or if in MKX we had Triborg in this we'll have a general Robot with the custom favorite traits from Sektor, Cyrax, or Smoke?
