As time is passing, more and more people are finding that the Warlock is the best class in the game. His Nova Bomb is the most versatile put of all. He can throw it at his feet and mimic the titan. Or he can throw it long distance and kill more people at once than the hunter's golden gun can. The warlock is meant to be the least resistant to damage. He's for players that make a constant effort to not get shot. Because his attacks do the most damage, offensively. The gear drops are random. I have an exotic helmet that's about as good at the Titan chest armor you mentioned.
