Of course that's a sort of problem all such stories face, though I've cited before the instant fail of Knightfall (for me) because Batman brings his anal retentive possessiveness of Gotham to a whole new level of "stupid".
My point, and I DID go out of my way to stress that this should be a Nightwing only resolution (and not an overused one), is that this story could have been a chance for us to see how a plan that MIGHT work against Batman wouldn't work against Nightwing because he doesn't react like Bruce would. He's not afraid to call for help (and his friends would be furious with him if he didn't), and he is repeatedly pointed out as being the most trusted and well liked superhero aside from Superman, except in this arc.
Instead, this arc didn't present us with Dick Grayson, it presented us with an vastly inferior version of Bruce Wayne... or an even more inferior version of Matt Murdock, since Dick crumples when Matt did not.
