In my opinion. [b][u][i]Titans[/i][/u][/b] In the lore, it's always the titans fighting these huge battles, (twilight gap, burning lake, hell they're insignia is based off the six fronts) There's a reason why he's [b][i]Commander[/i][/b] Zavala, Warlocks may be the most intellectual of the three, but they're scholars, not fighters. Hunters, would probably do the best in small battle tactics, enviorment scanning, guerrilla warfare, etc. But they just wouldn't have to coordination, I doubt they would even care, as we see from our favorite Vangaurd Cayde-6, he doesn't care about these things Zavala stresses over, he wants to be a lone wolf.
