Changes I'm suggesting:
1. Wrecking Ball NEVER causes cascade.
2. Wrecking Ball can now be moved 1 tile with no cooldown, or with minimal cooldown (something like 1 in-game hour that would be roughly 20 minutes.) EDIT: this action needs to be restricted to people who have vandalism permissions to claim, ie. can't do it as a crime action.)
With this change, you could safely change locks in properly built airlock gates, AND demolish large sections of now-unnecessary walls without spending weeks on waiting 24 hour dry-times or having to build 10 wrecking balls.
