I just can't wait. It seems like most of the old combos still work. The 2C finisher became difficult to do like in MBAC. The MBAC nin combo is also a good option now (again).
Also the shin-nin into arc drive is a new addition, as the arc drive hits instantly now granted that you have them a decent distance in the air.
With OTG relaunch 214C enders will also be more common. In general a new play style.
