Assuming everyone has common weapons, and there is a mix of all the weapons. I would have to go with titans.
They have the most survivability. Warlocks are glass cannons and hunter are stalkers that rely on luck.
Major issue is that all the classes are balance fairly well, so it is hard to see which class would rise above the rest.

Well titans are built for war and use team work which gives them the upper edge

Built for war may be true, if it was a battle of attrition it would be titans for sure. As for teamwork, that doesn't seem to be a titan exclusive. Titans are great soldiers, durable, resilient and versatile. Warlocks are glass cannons, great alpha strikers and enormously powerful. Hunters are the sneaky, swift and lethal. I see no upper hand.
