Warlock main here. I’m not gonna talk about PvE since I don’t really play it or care for it much. However, in PvP, warlocks are the best class in the game hands down. Top tree dawn and chaos reach are the best light subclasses in the game. You can also play bottom tree arc which is A tier, bottom tree void which is is A tier, and stasis which is also A tier. Warlocks also have amazing exotics for PvP. Transversives Steps is the best movement exotic over Stompees and Dunemarchers. Ophidians Aspect is S+ tier. Geo Mags are god tier with chaos reach. Karnstien is S tier. Warlocks are way over represented in tournaments as well. Every team play double warlock with a hunter or titan. Honestly if there wasn’t class restrictions I’m pretty sure every team would run triple warlock. Warlock movement is the best in the game, they’re the fastest class and once you master their movement the have way more potential than titan or hunter. Warlocks are hands down god tier, the problem is you have to spend time and have a certain degree of skill to play them at the highest level. Most people rather just play hunters because they “look cool” and are extremely easy and forgiving for beginners. Same with titans minus the look cool part.
