Least used and still the most balanced. Also the best especially in PvP because 80% of the game in PvP you're not even using a super but maybe once someone's twice warlocks have the strongest melee on multiple subclasses, perks are phenom, and the grenades are just fantastic. The neutral game by warlocks is better than any class. Being good at playing warlock also requires you to be higher skilled due that it relies more on your gun play as far as effective working of the class. Warlocks have a higher skill requirement to it due to the unique structures of the skill tree and the supers themselves except for Stormcaller I feel is the best neutral game and super is aight. Titans lowest skill IMO. Hunters are the middle of the road to me.
