A lot of us that ascribe to the "Vision" theory dont think it is Batman who is having it but Wonder Woman. It isnt about Batman needing a reason, but why the heck would she get involved in a fight between the two? To me at least, I think what she sees is what would happen if these two go to war. Superman rules with an iron fist on one side and Batman fights him and his disciples on the other. She needs to stop it...
One thing that seems to get overlooked in the "Batman escapes Eye Laser" shot is that Batman isnt wearing the Mech Suit in that one. It is quite obvious that it is part of a different fight. As I watched the trailer again last night I had the thought that perhaps that was their first meeting, before they know who each other are. It probably takes place in the same scene Superman destroys the Batmobile and they face off. I think Batman is trolling Superman (for lack of a better word) to test his limits and to prove some theory.
This is what I do when I am trying to occupy my time...I doubt I am close but who cares
