Do people favor Pagodas over Cathedrals? I thought the artist specialist slot made the latter better? Did things change with BNW?
In BNW, Cathedrals have a Great Work of Art slot, not a Great Artist slot. Great Artists are now generated only by the Artists Guild (one per civ).
The cathedral's GW slot is the only GW of Art slot you can get in the early/mid game besides the slot in your palace and slots in some wonders.
