Currently if a player's food or water are yellow their blood regens at the minimum rate: 4.5 per minute and if their food and water are both white their blood regens at the maximum rate: 18 per minute. The food/water cap is very high in relation to how much food/water is needed to achieve white icons (with a chunk missing), it would make more sense if the blood regen rate was more granular. It wouldn't necessarily need to be fully granular like health regen, even just making it so blood regens at 9 per minute if a player has their minimum food/drink icons at white with a chunk missing and then 18 per minute if both their food and drink icons are fully white with no chunk missing would be a lot better.
