Remember, Bruce in a plain black get-up got his ass kicked by thugs in Batman Begins. He had to be "the bat" to amp his fighting prowess, and utilize criminals being superstitious and cowardly lots. What if he is fighting a mortal Thor who is used to fighting huge, ugly and intimidating frost giants, is supremely confident of his fighting skills and is not afraid of anything. What will Bruce, in plain garb, exploit then?
The reason why batman doesn't show his full fighting skill potential as Bruce Wayne is to reduce the risk of being discovered as batman
