In current versions, Ghastguards no longer fulfill their purpose of being guards stationed outside the Dark Tower. They fly around instead of remaining mostly stationary.

Ghastguards should be:

• Mostly stationary.
• Not look like the vanilla Ghast AI was kneecapped like in 1.7.10.
• Remain near the Dark Tower.
• Pose a real threat to people scaling the outside.
