Welcome back. As others have pointed out, the original Wrong spawn was how it is now; Wrong's concept, as I recall, is that it was an old, brutal prison, and most of the spawn reflects that. Most of the spawn can fairly be described as semi-ghostly, monstrous leftovers of brutal guards and brutal prisoners.
Wrong is the Sin or Anti-Virtue opposite the Virtue of Justice. As the Prison behind the Court of Truth is generally seen as a good prison, where the prisoners are generally cared for and Justice is enforced, Wrong is the bad prison, where Injustice was rampant and the prisoners were abused.
The Juka/etc. spawn was temporary; it was Blackthorn's staging area. And indeed when Blackthorn finally got impatient and launched an all out attack, it was on Yew: The closest city to Wrong. (Unfortunately, the team at the time, the AoS team, ****ed up and did not in any way involve the Juka or the Exodus monsters in the attack.)
There were complaints when Wrong was first changed. There were complaints when it was changed back.
