A huge Bat-Family, with multiple Robins and Batgirls, does not break the premise of Batman and instead gives us tons of great characters and unique interactions.
Batman no longer being one of the world's richest men is a massive step forward. It was an escalation of the power fantasy that was never needed.
People like Mariko Tamaki writing heroes as people first, with deep and complex relationship to their fellows and often putting character interactions before action, is a lot of books have lacked for a long time. I really want more of it. Her 'Tec run was a breath of fresh air. Sophie Campbell has been doing similar work on TMNT. Taylor's Nightwing, too.
Bendis' Batman Universe is a version of Batman I want to see more of.
Tom King's Black Label stuff is the most interesting and enjoyable uses of most of those characters in decades (in some cases ever). His Joker is best Joker.
The energy, life, fun and pure joy of Taylor's Nightwing and Waid's World's Finest, and DC seeming to take cues from them in recent books (Green Lantern, Superman, SHAZAM, Blue Beatle, etc), is making me read more DC than I have in years as I'd grown sick of the miserable slog. Many of DC's books are now actually enjoyable to read.
