Scouts would make sense, given their abilities and how they operate. I'm pretty sure a Warlock would be needed to really decipher what things are worth taking, though.

Exactly, maybe the hunter is told what to look for, but most likely they find something they assume could be worth studying.

If that was the case, I can certainly see how the rivalry would arise :P Warlocks: "By the Light, I'm surprised you idiots can even find the earth! What is all of this useless crap?! Hunters: "Woah, you guys are lucky we even went out to get this stuff for you! Show a little respect!" Warlocks: "Respect? Respect for wasting our time? [i]Humanity's[/i] time? Bah, just scout out the area for us and we'll send a proper Warlock to do the searching..." Hunters: "*Sigh roughly and walk away* Nerds in dresses... and these are the only guys who can figure all this complicated stuff out?" Titans: "... Hmph."
