I do want to ensure the Granary and Watermill have distinct roles. If the cost, bonus, and tech are close, then Watermills could be removed, and Granaries buffed near rivers. While Granaries with extra value near both particular resources or rivers would be reasonable and interesting, I avoid major changes like removing/adding a building when there's other alternatives.
Watermills previously gave -1to +1
and 2-5
(depending on the Engineer), and now are a fixed 1
3
, which I feel is relatively similar.
I agree; a large production bonus for watermills is much more interesting than boosting the food bonus; the strategic value of the watermill should be in providing production in river-areas that are often production-lite.
