What does Batman brings to the table
I know this isn't a versus thread, but since this section gets the most flow, i thought I'll put it here.
Like the title says, what does Batman really brings to the table in the schemes of things. I would like an actually reasoning why he's useful and not that he's the Batman answer.
Authors for some reason thinks its smart of them to make the human out maneuver the superhuman beings. With Bruce being the ultimate plot device.
So lets' look at the main JL, and what they bring and compares it to Bruce. For this, were only using new 52.
Strategist- Diana was trained by the God of war himself, nothing Bruce come with that she herself couldn't thought off.
Detective- Barry is a forensics scientist. Not only that, since he's the Flash, he's brain allows him to do his job far better than Bruce. Anything Bruce could come up with, Barry would have already though of it.
Martial Artist- Again Diana's being trained by her mother, the Amazons, and Ares the God of War himself.
knowledge- People always claimed how knowledgeable Bruce is, yet forgets there's a guy with a ring that as knowledge about the universe.
So again, what it is that Bruce brings that makes him such a powerful force that the authors makes the other Leagues act stupid around him and magically forgets there powers?
