Better combat. Maybe different stances like Rise of the Ronin/Nioh has. The current combat style is fine but could be a bit more responsive and tighter.
Like I don't know
>Beta Stance - Balanced stance but leans more towards abilities that gather Beta/Burst energy
>Gamma Stance - High Mobility stance, sword is held in reverse grip. emphasizes dodging and rapid attacks.
>Delta Stance - Low Mobility, emphasizes Parrying and builds attack power charged by blocking/deflecting. Attacks are slow but hard-hitting, sword changes form to be held in two-hands.
>Epsilon Stance - Medium mobility, attacks are low damage but sword is modified to be even longer and is adept at handling crowds and quick targets. Is also the only stance that incorporates the ranged attack drone into its moveset.
