I agree, weapons need more tweaking, coz right now when you upgrade some weapons it feels more as a downgrade ... again thank you for your inputs :) and plz rate the game...more interest --> more dev time.
Something popped in my mind as a suggestion for the bow. If you happen to decide to make it as fast as the hammer, maybe limit it to 2 or 3 arrows at the same time. So if you shoot a 3rd or 4th arrow the first arrow will just disappear. That could prevent people from spamming the bow.
