One, nothing was really done to make us wonder who was behind it.
Two, who leads the Court? Well, it was implied that the Court itself did the leading, or perhaps that an old woman in a wheelchair was the key decision-maker. The reveal of the identity wasn't a whodunit moment, but a what-is-being-done moment. "Look, I'm so nasty I am manipulating both the Court and the Batman! Ha!"
For me, it wasn't the hidden identity that was the problem. It was that I didn't realize there was an identity to even reveal. And that the motivations of the Court, never very clearly defined, became even more muddied as the arc progressed.
