During our first playthrough of this game we found that some of the plastic units in the game are very limited, based on the mustering capacity for various houses.
For instance, each house only has 2 plastic units for Siege Towers. When mustering, does this mean that a player's armies are limited to 2 siege towers in total, or just that the player needs additional tokens of some kind to identify them?
I can see both arguments. I can see an argument that units in the world are a finite resource, but I can also see a possibility that this is just a limit in the number of pieces provided and as long as players can track their armies and their armies conform to the supply rules they can have any composition they have the mustering capacity to create.
