I might be wrong, but the combat looks more responsive? It seems too easy though, I hope they ramp up the difficulty later on in the dlc. And yeah, the presentation looks much less amateurish than in the base game. I'm cautiously optimistic for this and the other episodes, I'll probably buy them when they're all released if they're any good.
Liking that battle theme, sounds like something from Crisis Core, fits Gladio pretty well.
