Yeah, that's true. But if you look, the attack enemies in the new footage seem to be trying to launch big attacks, but Noctis' furious assault is continuously knocking them back and delaying it. It sounds like an exciting risk-reward system: judging the enemy's health, taking the plunge and going in fast during an enemy's vulnerable period pre-attack - a strategy that could go horribly wrong if timed wrong.
Personally, the new look seems more realistic. If you think about it, those kinds of fights in real-life would probably have knocks being anything from inconsequential to giant-felling depending on the power and placement. It invites strategic thinking more than just barreling away (wish they could have fitted that into LR, that would have made the battle system close to perfect).
