I slapped together this mod because of a complaint that was expressed. The Warrior goes obsolete at Iron Working in the vanilla game. If you don't have access to Iron after researching Iron Working then you are basically S.O.L. Now the Warrior goes obsolete at Military Tactics. Let me know if this works. I put this together without having the game unlocked. I used MadDjinn's and Rob (R8XFT)'s mods as templates. This does not account for Warrior unique replacements. https://www.dropbox.com/s/dja3jqtshpdnlci/WarriorObsolete.zip?dl=0 Unzip here: My Documents\My Games\Sid Meier's Civilization VI\Mods It should create a folder named: WarriorObsolete Be sure to activate it in the game under Additional Content.
