You said there was gaudy zoom and slow motion (implying that was different from NG2's OTs) and I said it looks like it takes the same amount of time, maybe less, and that it isn't slow motion so much as a brief pause during impact. NG2's camera did all kinds of crazy shit during OT, including zooming in, so I don't see how that's a valid complaint here. All in all, it LOOKS no different from OTs. So that's the part of your post I didn't agree with.
The point about whether it's random or not is a good one and I don't know how it works. Have they said definitely that it happens randomly instead after the enemy is sufficiently weakened? If it's random, then you have perfectly reasonable grounds for complaint. If it works just like OTs then all the bitching about it is ridiculous because it doesn't disrupt the flow any more than OTs did.
