-Dick Grayson should still be Batman, Dick was way more interesting than Bruce returning as Batman
-Bruce should of never return to the Bat Mantle after he came back, He should of instead became something like the Oracle especially in the New 52
-Tim Drake should of never been called (the laughable) Red Robin and instead he should of taken over the Nightwing Mantle during the whole transitioning period.
-Bruce should change his mind and get more seriously into a romantic relationship instead of the usual temporary love interests
-Batman needs more diversity in his Robin lineup than the usual straight caucasian child he finds like why can't Tim be interested only in guys and also be half Asian?
-No live action Batman movie to this date really captures Bruce Wayne/Batman.
