Cool stuff, I've seen some attempts at porting DOA3 characters to DOAO, but never DOA2U to DOAO until now. Honestly I wouldn't really play such mod with myself, but it would be awesome if DOAO had it. Maybe, should the client ever be "revamped" at some point... let's keep the DOA2U movesets ready to be implemented, definitely.
This is what I found:
P changed from i17 to i12
3P changed from i20 to i16
6P changed from i29 to i18
6PP is also faster, but I couldn't tell if it's exactly the same speed as the new 3P. It might be one frame slower at i17, since the 2U version was also one frame slower than the old 3P at i21.
I can send you everyone's 2U data if you're interested in messing with it. Just for fun or to document the changes from 2U to O.
