With the lack of showing us much of melee outside of pistol-whips I'm kinda worried the animations are going to be stiff and wonky again. If it got improved I think they would have shown it a bit more instead of focusing on ranged weapons.
That's one thing I always hated about 3/NV; melee/unarmed was very awkward...I just couldn't even force myself to do it in 3 or NV. I don't need combos or excellent animations, just something similar to...idk, Dying Light would be satisfying enough.
