Nah, Bruce should definitely have stayed dead, it would have actually been the greatest thing ever. If Dick had truly taken over and Damian was his Robin it would have been genuine progression in a comic book. It would have been ground-breaking! Every time in a comic someone else takes up a famous hero's mantle, the original is back within a few months (see: Azrael)
Dick becoming Batman was literally incredible for me, as it felt like for the first time there was progression to a universe, y'know? I honestly thought they might keep it that way, and it would have been good, Bruce has been injured so many times, he died heroically and it was all so very, very good. No hero should live forever in a comic book, but sales-wise they have to. Instead of characters legit growing older etc. things get rebooted instead, and that sucks. Notice how all the older characters like Jay & Alan Scott are waaaay younger?
Best thing for me in comics recently: Death of Ultimate Universe Peter Parker, and he was a character I absolutely loved to bits! Like, I have over 100 issues with him as Spider-Man, but when he dies it is truly an awesome death, and everyone finally recognizes how great he was, and that he was just a damn kid! And the progression with Miles Morales feels so genuine!
TL;DR: Bruce should have stayed dead.
