I honestly don't see how the hunting skill can help with other skills.
As much as I hate the farming skill (and I do with a passion) I do acknowledge that you can grow strawberries and watermelons which are fruits you can't get any other way, and these are used in cooking to make summer pies. Doesn't mean I'll ever use that skill though because like I said I hate it, I buy the watermelons and strawberries I need from the grand exchange instead.
But with hunting, I have no idea how that skill can be useful with any other skill. Can someone fill me in? Is anything, ANYTHING AT ALL that you can only get via hunting which can be useful in other skills? Any help would be appreciated.
