One of the biggest changes I would like to see is the buffer and engine to loosen up and feel a little more fluid. Though, I may be in the minority there. At some point in one of Doa5s patches I felt the changes to the engine while minor, made the game feel stiff and it seemed to eat inputs like...
Best friend: Homura
Love interest: Rin
Rival: Katsuragi
Tag partner: Ikaruga and Asuka
Number of outfits: .50 clothes are overrated
Affiliation: Hanzo Academy
Won against: Haruka
Defeated by: No one! Freaking Daidouji!
Fighting style: Nobody has more style then me!
Bring on Senran Kagura cross...
As soon as I have some time I will be back to add my 2 cents. Ohhhh what a whole Lotta text *pick slide* unfortunately we all do know Ein needs some help. I am an advocate making small and few changes as possible to make him logical but effective.
