I posted same video. Combat becomes exactly like that if you invest in certain builds and skills.
Combat is not bad but it takes time to get good. Combat wise Shadows is better than any AC game, huge improvement in combat, you can check any reviews, every single review give high praise to combat and call it huge improvement compared to old games. Main story is weak and forgettable and some stuff is boring but combat and stealth are quite good.
Here IGN quote -
Aggressive and Intentional:
IGN notes that the combat in Shadows is "aggressive" and demands more intentional parrying and skill management, moving away from the more forgiving systems of past
