You aren't missing much with the wind staff. I've upgraded and used every staff and it's the first one to stop one hitting and it's in the early 20s. It's charge shot is arguably the best as it creates a tornado that insta kills normal zombies and has a mad range but uses the whole clip of ammo. Not to mention the wind staff has low ammo anyway.
Though back to the topic. It all comes down to the story for me in what makes this worse than BO1. Gameplay is great minus the fetch missions but the reason I got hooked on this game when I have traditionally hated COD titles is because of the wacky yet extremely captivating zombies timeline. It lost me with this release.
