Look, i'd agree that something about cooking needs to change. Right now, it is not worth my time waiting 5 minutes to cook 1 complex recipe, when I can pump out 20 cooked steaks for more overall stamina. It requires too much time and babysitting.
But I believe the problem is the upper end of cooking (and food) is balanced wrong, not the lower end.
Complex recipes are locked behind items like salt and pepper, which drop from one encounter (in an area that doesn't have WW encounters so no one wants to go there) - they are now sold for tickets once every 2 months or so but it's not enough. Recipes should either remove the need for stuff like salt or pepper, or have it constantly available for purchase in the MM (or also add a WW encounter to all locations).
Some recipes need to drastically reduce / change ingredients, the pot should be bigger, or possibly both. The limited number of cooking spaces for recipes like wheat means these recipes are essentially useless; and then locks out the higher recipes as expanding the cooking pot is locked behind premium currency - sorry LW but I am not spending $20+ dollars on cooking, and i'm not wasting my time cooking 6 wheat into 1.
As far as stamina goes, I don't agree with a straight out nerf, if it's *only* a food nerf (no surprise, right). Campaigning is a ton of fun, and these changes seem like a reaction to one person abusing the campaign. You can burn through a whole bar of stamina in 2 minutes from average campaigning.
Nerfing food stamina will nerf the biggest drawcard and structured activity on the site and you will see a significant drop in activity onsite if it's done wrong.
If stamina points were to be nerfed, then it should be balanced by more passive ways to regain stamina other than just waiting an hour or so, such as removing the swap out timer on wolves, significantly faster regeneration of stamina, lower the stamina cost per encounter, increase the food drops in campaign etc.
Long story short, I do think careful and well-balanced changes could have a positive impact on the site and make cooking more desirable - it should be desirable! But it will kill a lot of interest in LW if you make it impossible to play for long periods of time (or really more than 2 minutes every 15 minutes) because stamina is so restricted.
