HoneyBadger has created a thread in the main dominions forum containing his wishlist/modding suggestion:
Wishlist: Multi-Tier PD
The original content of this post can be found at the above link. HoneyBadger felt that the content was relevant to this thread and the Mod forum, but to allow extensive discussion of the suggestion, he requested that I edit this post.
Have a nice day.
