Thank you for making these videos, we need this kind of bug reporting.
The first video with cutman anctually isn't a real Infinite Combo because if Sabre was being controlled by a real player he could easily block after the air combo to avoid being comboes a second time.
As for the Wolverine one, although it is fairly difficult to perform, it looks pretty legit once you get in the pattern. Thanks for the info. We'll definately use it.
