>>1950226I see your point--for a non-tournament player it's less of an issue, but still a valid one. That being said, that doesn't reflect on the actual personalities being introduced (or borrowed from other franchises), but reflect mechanical deficiencies.
On the other hand, I completely forgot about Nyotengu, easily one of the better DOA5 new characters. Still not as good as Hitomi, Christie or Lisa but still a strong addition. So they did something right without him, at least. I'm probably a little biased by the fact that DOA5 has the terrible Soulcalibur V-style story mode as oppose to the safe, boring, but at least not awful story modes of the previous games.
In any case, Itagaki is equally responsible for DOA3 (and its updated form) and DOA4--in my own limited experience, I'd say DOA3.1 was far better than any incarnation of DOA5 but, again, it's not my area.
