I disagree with your suggestion. As the game's title says, it's called "Lucky Islands", all is based around luck. That means you can get a quick end to your life or a thor's hammer. In this particular case, this automatic bow is pretty useful, specially if your opponent has a considerable advantage towards you, meaning you can use this bow as a last weapon to defend your life against a "well-dressed" player. I know that, on the other hand, this bow can ignite the frustration of almost all players, but, in my opinion, I don't think it should be removed just because of that.
Also, you can always defend yourself in time against this bow, for example, you can always place blocks quickly, or move from side to side, or even you can use a shield to defend against it, which it's the best case.
