So a lot of people say that a certain subclass is the best, and they give plenty if reasons to support their opinion. I am personally a master race towards the warlock, and here's why. Let's start with the Sunsinger class. I think that the Sunsinger is a very good class that is meant for longevity and survival with Fireborn and Flame shield, with their super providing things like radiant will and radiant skin. I personally use this class in every raid mainly because it can be the most useful. Their grenades can weaken shields, or straight up kill. Fireborn gives your fireteam a player back when you die. Also, the sunsinger subclass generates the most orbs with Light Beyond Nemesis. Exotics for the sunsinger are specified to lengthen your radiance and disable enemies when activated using purifier robes. Overall, sunsinger is a favorite of mine, and is meant for Longevity and survival. P.S. A good combo exotic for sunsingers are Claws of Ahamkara and Monte Carlo. Claws gives you 2 flame shields and Monte Carlo will constantly recharge them :) I will post other warlock subclasses later
