My money is on the intellectual stuff. Hunters try to be clever, while warlocks try to be wise. If you imagine the stereotypical hunter, I imagine a clever jokester with an attitude and sarcasm (basically cayde-6) but the warlock tries to be the mature, wise one of the group. so you can see where the chaotic hunter would butt heads with the lawful warlock. The titan on the other hand can either be the meat headed fist of power or the leader that is far too mature to even stoop to our level. also: if hunters taught warlocks, warlocks still perfected it. if it's the other way around, then the warlocks are the wise sensei (wax on, wax off, my hunter protégé) P.S. I admit to "floofing about" with loads of pride.
