I'm going to really answer your question now: So, bassically the Warlocks are the Noble People, they are the high-society wizards. They don't want bandits in the Tower, because they act childish. But they need to realize those bandits can actually help us.

Umm....I like titans

EVERYONE look up Adam warlock.....this is why warlocks are better.

I got one pair of boots for my warlock that makes me laugh every time I think about it "If a Hunter ever says that you took his kill simply reply 'Your aim was untrue and therefore I could not abide by it' " Kills me every time I think about it. It's kinda appropriate though cause my brother plays hunter and he and I kinda just fell into the same type of teasing the game has in cannon. Alas. I think that Warlocks and Hunters bicker because they are inherently different play styles(cannon wise). One is one who supports the group and the advancement of the race. While a hunter is traditionally a lone wolf. So I imagine that a warlock would be disappointed in a hunter for not being more of a team player and the hunters like "whatever. I do what I want"

I think it's cause warlocks will always be the third wheel. Cause titans are leaders. Hunters are rogues(bad asses) and then you have warlocks. The third wheel of the relationship lol.

I eat hunters for breakfast, titans for dinner, and warlocks for desert.

It's the war between cloaks and trench coats. Which one is better? We may never know...

Probably because Hunters tend to shoot us Warlocks in the head while we tend to nuke their butts :) Seriously though I noticed that too during beta, but it is a nice rivalry as far as lore goes. During beta every piece of green armor I had made some reference implicitly or directly to Hunters, making fun of them, criticizing their methods in someway, stating how are Warlock method is better etc. However, it does makes sense if you consider the following: From what we know us Warlocks are essentially the Sages of the Traveler and harness its power purely for intellectual reasons, hence we're philosophers at heart and love the knowledge bequeathed to us by the Traveler. Weaponizing it is secondary to us. Thus we're the brains behind Guardian resistance to the Darkness. Titans arguably are the brawn of Guardian existence, but protectors of the Traveler--which is exceedingly important. So if us Warlocks are the brains / scholars and Titans are the brawn / defenders, then what are Hunters? Well Hunters are essentially loaners, drifters, and out for themselves with no real or at least definitive purpose as to how they help the Traveler. Hunters are also fundamentally explorers traversing what's left of our civilization's remnants, and utilize the Traveler's light to punish our enemies. In essence Hunters are really traveling around trying to make our universe safer for us again, all by themselves--definitely a most important task. Thus in a sense I think Warlocks and Hunters are diametrically opposed to each other philosophically; Hunters see harnessing the Traveler's light for knowledge sake as a superficial use of this power whereas Warlocks see harnessing the Traveler's light just to simply destroy our enemies as an excessive waste of what it should be used for. This is totally speculative on my part and just my 2cents, but hopefully we'll find out more about this rivalry post 9/9.

Titan is the tank. Hunter is the over watch and The Warlock. The Warlock is the Honey Badger. Edit: Warning Explict language in this video you've been warned.

They can't compete with Titans so they're just trying to secure second place.

You know, I don't know where this amazingly petty rivalry comes from, but it just makes the choices for the voice actors for the Hunter and Warlock Vanguards so much more awesome.

I think it's more of a friendly competition. Titans are kinda left out because they're more of the backbone soldiers defending the wall, they don't have room or time for that. Hunters and warlocks are the ones with free time beyond the wall and studying the travelers mysteries. I see it this way: the titans defend the wall, there's no doubt what they do helps mankind, where hunters and warlocks are constantly trying to prove they're still worth what they're made of

Scissors beat paper....(hunter beats warlock) thats why.

I am a Warlock. I have unlocked the arcane secrets of the traveler and use them to banish the darkness into oblivion. The Darkness cowers in my shadow, and the innocent stand proud at my back. I protect, I serve, and I will put an end to the Darkness. But what I will not do is claim supremacy. I will not lie, for all my wisdom and determination, a Hunter will always be the first to a fight, and a Titan wont stop fighting until the fighting is done. Though those "bandits" may be unreliable at best, they bring us swift and silent victory. Without Titans we would have been overrun many years ago, for they have a strength and fortitude that we all can aspire too. I am proud, but not only of myself. We are all heroes. Only together can we cast a Light strong enough to break the Darkness. I am a warlock. But we are Guardians.
