I think it's because hunters(in theory) are brave and bold. They head towards danger with out flinching or thinking twice. The wild is there playground. Hunters- rebel
Warlocks(in theory) think before they do everything. Everything must go as plan. That's why they study so much. Instead of heading towards danger they like to gather info on the enemy. So for them seeing a hunter be so crazy and still survive doesn't make sense to them and the warlock hate the hunters for that. Warlock- follows a rule of some sort.
[spoiler]its funny how the warlock study the light(powers) a lot but every guardian can use and weld the light just as/better than warlocks[/spoiler]
