Well, warlock is the mid range fighter class. Making it very adaptable to fight with in every situation. It has good passive making it easy to max whatever stats you value. Nova bomb is a beast but it can also kill you if enemies are to close to you. The area of effect grenades are both pretty good in pve, especially with enhanced duration. Axion bolt and bloom is like a mini super and scatter grenade combined with bloom makes so many dam explosions but is also very lethal to yourself should you be to close to whatever you threw it at. Sun singer is very mediocre however in terms of raw damage, it is a very controlled ability. If your dying a lot then this is the sub class for you. Apotheosis veil makes radiant skin or even song of flame useful to both getting health and being a tank or helping your teams overall DPS. I'm excited for the ram exotic helmet to blind enemies with my self res and purifier robes for a bloom effect on sunsinger. Especially the purifier robes. I feel like that will give it a stupid amount of destruction and survivability. In summary, warlocks are great but like the other classes they are flawed, people without a warlock can point and say self res is OP but it's really not, sunsingers total DPS capability makes it very difficult to kill large groups of enemies quickly like you need from a super, without good weapons the subclass is support at best, a safety net. A Titan bubble is infinitely more useful for a team while self res only saves you, a very selfish ability on a raid and typically does not save your team from wiping often. Hunters have great DPS supers but can seem a bit weak vs elites. I very much miss my hunters as they are a high risk high reward character, very exhilarating to play when shit kicks off. I look forward to seeing the new arc subclass, I hear it has DoT capabilities which is intriguing but I fear it could be far to weak like sunsinger is currently, I hope they bring a few good exotics with the comet dlc for it to boost up its damage. TL;dr warlocks are good but balanced, I want purifier robes, warlocks are a selfish class. Titans are more useful, hunters are fun to play as.
