The movie doesn't mean nothing in this regard. This isn't overreaction to not being able to use Claptrap's voice in the fight scenes. It's just something that makes no sense in any way. If we're going to make big moves in big fights, shouldn't we be able to call out bad guys and change things up a bit? That was never going to happen in this fight scene because none of us can speak for Claptrap. But don't take my word for it
