Yes she is physically weak. I think i explained why. And the fact that the person she was trying to kill is Lucy, a fragile person, doesn't make her intimidating. Also, she surprised her. She had the element of surprise and she was still unable to finish off Lucy. How is she not weak? She is not Lucy-like weak, but still.

In any case, i think Hiro plans to make Brandish change sides, so that physical weaknees of hers won't be exploited. It's not like she can escape from Fairy Tail with the magic seal stones and now she lost the chance to kill Lucy. Now she will hear the truth about her mother from Aquarius and then she will shift allegiance. FT won't let her go and she can't escape. So what's left?
