Please note, I have never played MKD, so I am only going off what I observe in the videos. The character moves looks so much like a copy-paste of MKDA. I see many of the same moves, the overhand punches, the falling down, the spear, kicks, etc etc.
Many people believed in MKDA character to character didn't vary the way they moved enough. The moves were also not very "natural" or fluid. A large concern of mine is playing this game and it feeling like MKDA with big backgrounds and new characters that move like robots.
Just my opinion.
