I did pop an online match.
Seems those bosses you want banned aren't even selectable.
It was a bit laggy but it was 140ms ping so some input delay is expected. Wasn't terrible and was decent given the circumstance, I suspect below 100 will be better.
Got my play my in-state daughtero, and at around 40 ping it felt good.
So I guess my verdict is this is around SF4-level netcode and probably ok for half-country play, but not coast-to-coast.
Controls did feel a bit off, but that could be pad buttons.
Also a Hori FC4 set to PS4 settings will not be recognized, had to set to PS3 settings.
Netcode is not good enough for me to buy a non-rollback SNK game in future- this hits me in the feels, so I could tolerate shit I wouldn't with another title. This netcode is mildly shitty.
