In the lore its kinda like jocks and nerds... Kinda. Warlocks consider hunters rash and impulsive (and kinda dumb). There's a grimoire about a warlock telling a hunter how impossible it would be for her to kill an ahamkara and the hunter instantly takes it as a challenge, the warlock thinks he's killed her because of it. Hunters don't necessarily think 'less' of warlocks, just that the hunter's "get out there and -blam!-ing do it" attitude is very different from the "academia" approach that warlocks have. That and there's a hunter armor piece that tells the story of a hunter who refused to shake any warlocks hand cause the fear of being vaporized. In-game wise.
