The town hall could be also a defensive building when builders and peasants garrison inside. They could shoot arrows, use pikes and pour hot pitch (tar, resin).Â
This may improve defense and increase utility of these buildings. Also it will help preventing players to intentionally place their town hall in the open in order to downgrade their league.
I hope somebody likes this idea. Yet, I apologize in advance if this has already been considered/dropped-out. I just couldn't find it so I post it.
Regards.
