In your opinion...
Storywise, Kung Jin. Felt like they threw him in just because. Not even a peep, cry, or hum of how he felt about Kung Lao. Not even much of a role in the comics (yet).
Gameplaywise, definite Kotal Kahn. Just slow af (even more than Goro and Torr which is sad). Sunbeam move is not as cool as the comics. Can't double buff damage with blood code and strength totem active. Air Grab move is a waste of resources that could've made a new move for him that's actually good.
I don't know why everyone thinks Kotal is the worst for gameplay. His mixups are INSANE in War God. Being slow =/= bad.
Definitely Tremor. He's also the worst ninja out of all of them.
I may be hung for this , but I hate Erron Black. He has minimal story involvement outside of being a lackey. The only real difference between him and Baraka or Reptile is he gets paid for his services. He still gets his a$$ handed to him throughout the story. Plus I don't see where his design is so great. He's a cowboy......I fully accept the wrath that will be unleashed upon me for my comments.
