GB ends up being a 35% buff when you have improved law system and 25+ castles or a 55% buff with 45% ‘castles and no improved law system
It does not need buffed. We just don’t have a kingdom in the game, big enough to take full advantage of it right now.
IMO it’s ridiculously OP. What do gnome or dwarf get to compete against that?
Balancing issue though and something to be addressed later.
