Well, considering V2 and V3 were planned as one volume, and V3 ended with a Grimm invasion... perhaps they just didn't change the script? They got stuck with a Grimm invasion that couldn't do anything major, because the tournament still had to happen, and Cinder had to make another Grimm invasion work.

If the first one had done more damage, not only would the tournament have likely been suspended, but Ironwood would've called in a larger army, and Torchwick would've been percieved as far more dangerous and likely sent somewhere other than his simple cell on a random ship.

So they really couldn't make it anything but abrupt and keep logical consistency.
