Wave slash is a cool skill. It’s unique. It’s flashy. But it kinda sucks.
Practically never use wave slash for any actual combat. The tiny orb to strike just makes it not worth it. It stays in place relative to the world and not the player. Practically any movement will throw your aim off, most likely.
Not to mention, when enemies start popping up, you have to raise your weapon and wait for the orb to appear, and stay in one place during the entire endeavour. This puts you at some unnecessary risk compared to the other skils.
Possibly change it so that the orb at least travels with the player? Maybe even moves with HMD movement? It’s just inconvenient to use.
