I'd like to see a return to families of characters. Before Infinite Crisis, the trinity had families of really strong characters that built up around them--Superman had Superboy, Steel, Matrix-Supergirl, and some others, Batman had Nightwing, Robin, Oracle, and Batgirl, Wonder Woman had Wonder Girl and Donna Troy. Now a lot of those characters have died, gone crazy, or been replaced by inferior versions, and the ones who are still around have distanced themselves from each other a lot. Nightwing and Batman are back to the strained relationship they had in the '90s, Robin is now a clone of Dick, Steel hasn't really been mentioned in any Superman books, etc. I miss the days when a big Batman event would have the whole Bat-family pulling together and relying on each other. I'd like to see some more of that.
