They need to bring the personality that Ayane has in Ninja Gaiden to Dead or Alive.
Damn, if they want collaborations so much, just make a Ninja Gaiden DLC pack, i know it is the same universe, so is not collaboration, but i honestly think DOA as a series needs more of Ninja Gaiden and vice-versa.
About the AoT dlc in general, really terrible...
I still have hope that my designs are chosen for the halloween thing.
Story DLC?
Do a new story mode that covers from 1 trough 4, changing the bad things of dimensions (so, make Kasumi defeat raidou by herself, and make Ayane defeat Omega by herself, remove the suicide thing, Ryu already defeated way more terrible creatures, he can chill in DOA).
Also, i would really love if Team Ninja went back and revised the inititial plans that Itagaki had for DOA 5, the whole thing of Ayane Killing Miyako.
Also more progression things like Ayane using an outfit that shows that she is the head of the hajinmon sect, Hayate not being a jobber anymore and actually doing something.
Make Honoka have plot relevance, since she is related to raidou somehow, Marie Rose being secretly one of donovan's top agents or something.
Also, bring back blood in scenes that should have blood.
Sorry for the rant.
