All +Ranged foods require fished and farmed items, and fishing and farming are the most tedious of gathering professions. There's no logical reason why rangers should be eating fish that much, it'd be easy to switch some recipes.
I'm a ranger and I've been levelling my cooking, I can make +20 Melee and +20 Sorcery foods using raspberries only (plus purchased components), but for +20 Ranged food I need 2 bass and 2 onion and 1 pepper for each. That's crazy. Don't even want to think about Cooked Mackerel...
