Hanzo has the best passive of the three, but has two specials that are basically the same. Lame as always.
Kintaro is just his MK9 appearance, with Goro's throw from MK X as special 2. Lame too.
Bo' Rai Cho is the only character in which they put some creativity into. His moves are funny, his animations are good for a mobile game. His flask is yellow, while it should be red in his fire breather variation, minor hiccup.
End of the story, I hope there is more in this update because 1.17 is very barebone as it is.
Next update will likely be the next Anniversary update. Thats when Shang will likely drop. Theyve also been promising some stuff to be added to Faction Wars store. Before all is said and done we are definitely getting Leatherface and Shang. On top of that, Rain and Sindel are just as highly likely. I would also wager since Jade made it, Noob might as well.
