The Fay Enchantress faction trait now gives +10% income from farms instead of -5% upkeep to sword infantry

Slightly improved the replenishment from the Improved Mills and Empathy techs

Vows now give a -10% upkeep reduction for their corresponding knight units
Industry income reduced from 200/300/400 to 200/250/300
Industry techs give slightly more income to compensate

Developer thoughts:
Vows are still purely beneficial, rather than preventing a massive upkeep toll, but this should keep them useful at gatekeeping late-game knights to some small degree. To ensure this is the case, industry is weaker in the early game (but still better much better than farms, especially if you are deep enough into your campaign that you have all the techs for industry)
