Another vote for the return of the face. Him not having it does nothing for the character.
Yeah, it's pretty much the only thing from the New 52 Batman stuff I don't like. It also doesn't help that its from the part where the start of Detective went meh with that doll maker stuff.
Joker's face being cut off was at least partially Snyder's request. When the early issues of New 52 were being planned, the Bat-editors wanted to keep some of the big villain names out of the picture for a while to give the writers time to develop some new villains of their own. Tony Daniel offered a few suggestions on how to remove Joker, one of which was Joker's face getting cut off. Snyder then requested that idea, because he thought it would tie in well with the story he was planning for post-"Court of the Owls."
I'm not saying that that makes the idea better, just clarifying that it wasn't only Tony Daniel involved in the decision.
