You should really note that because of damage proration changes his old combos do substantially less damage. Because of this they are far less worth while in meter cost and execution difficulty to perform. He has new toys but there are certain old (and very powerful) tricks he simply isn't going to be using anymore. That combo you've hashed out there probably won't do substantially more damage, will take more meter and doesn't give the strong (all be it bread and butter) oki of a KD into 3D, so doing stuff like that, while perfectly feasibleness, may not be worth while. I've you've ever fought against Soujiro and seen how he plays, new carl essentially craps all over his play style. its why he's unenthusiastic, and to an extent he's not wrong. His play style has changed significantly, and the optimal way to play him seems notably more clear-cut.
