It narrows down to the argument of: Which is the better intelligence? Common Sense/Street Smart or Book Smart/Education? Hunters probably live by street smart. Don't walk there, don't eat that, don't poke bears with sticks. Warlocks always are trying to adjust strategies and finds ways that make things easier with ploys of predicatable patterns, etc. So, in the moment, just doesn't work for them. Warlocks spend time educating themselves on things, and Hunters view it as a waste of time.
