The thing is that most writers bring back characters and there usually isn't consequences to their return at all. Superman comes back and its like "oh great to have you back big guy!" but there should be a fall out from that. I wrote a book a few years ago and I had two characters die. The emotional weight behind those deaths were brought to the other characters in full force. They questioned what they should do and where to go from there as they continued to look back before they moved forward. This is why death is important in comics.
I digress though, Dick did a lot of this when he took up Bruce's mantle, but when Bruce returned, Dick was like "well I guess you're gonna be Batman again. See ya!" and it made the whole story of Dick as Batman kind of irrelevant.
