If an argument for him attacking Gotham for any other reason than Talia is to be presented, it needs to be done so with solid evidence from the film. This debate has been going on since the movie was released, no one has managed to find anything to show that Bane would've had a vendetta against Bruce/Gotham if not for Talia. The movie explicitly tells us that Bane was excommunicated from the LOS then inexplicably doesn't explain why he would be so devoted to their ideals in the first place
Again, whether or not this is a good enough motive is up to the discretion of the viewer. But based on the evidence presented by the film, it is the only clear motive presented
