So, I made a patch that adds the Practice Range (aka "Archery Range") as a buildable structure.
Enables Practice Ranges for all civs, which train Ranged Infantry
Adjusts costs for the Barracks, Range, and Stable to compensate for the new building
Recreates the relevant technologies from the Barracks over to the Range
Moves Archery Tradition to the Range (and Hoplite Tradition to the Barracks, as a mirror)
Some other minor things
Please playtest with multiple civs.
Look for and critique:
