Warlocks are not agile (trust me I main one) they are good at what this game has for tanking and are great for clearing mobs, I also like void for pvp over the popular stormcaller as I feel stormcallers are too easy to kill (probably the easiest to take down but also can net multikills often). While my character of choice they are often seen as least useful for raiding (for reasons I do not know). Imo they are the best solo players choice. Hunters are imo best option for pvp gunslinger is my choice for both solo pve and pvp (gunslinger combined with celestial nighthawk helm has highest single damage super ingame). In a group I tend to go nightstalker for pve and occasionaly Ill go into pvp as a bladedancer but only since dual skip nades came in after the april udate nerfing of gunslingers tripmines. Titan I play the least mainly due to me being a solo player and titans are at their best in a team (imo of course) For pvp I always roll striker Pve I tend to go sunbreaker and Ill only run Defender if a bounty calls on void abilities to be used. (I dont raid so defender isnt useful for me but for raiding/nightfalls is a great class and good orb generator alongside a nightstalker or gunslinger)
