1. Projectile reflection - The Hunters have Whirlwind Guard, allowing them to reflect projectiles. The Titans have Antaeus Wards, which they can use to slide and reflect projectiles, the Barricade blocks damage from one direction, and they can block with Sentinel Shield on all subclasses. 2. Suppression. Titans have suppressor grenades that can shut down Supers if used correctly. Hunters have the Void Super that can tether and disable Supers. 3. Melee-Ranged Supers. The Sentinel Shield can be used both for short-range melees, and long-range throwing of shields. While the Arc Hunter Super is mainly a meleeing Super, it also has medium-range with the heavy attack (and combo capabilities). 4. One-Hit Kill Melee abilities. While each element of Titans has this, the Hunters were recently given knives that can one-shot enemies if they hit the head (and get replenished when they do so). Warlocks have none of this. Their Rifts may heal and empower, but they're completely stationary and leave them vulnerable. Even the Well of Radiance leaves you wide open to damage, particularly damage from other Supers. They lack the means to shut down other Supers. No ability, no Exotic. They have to expend their own damage-dealing exotics to counter another (Hunter Tethers have greater utility than just "counter Super). Dawnblade was one of the new classes in Destiny 2, but it was the only one of the new Supers WITHOUT melee capabilities. You can't block with it; you can't use melee with it. It's solely ranged attacks. Nova Warp is the only roaming Super [b][i]that needs to charge[/i][/b] before it does damage. Titans and Hunters have immediate melee attacks. A Stormtrance Warlock has to deal sustained damage in the time it takes for a Hunter or Titan Super (or even Nova Warp). They lack one-hit-kill melee abilities. The closest they come is Handheld Supernova. But while Hunters have one-hit knives that refund Melee energy on precision kills, and Insurmountable Skullfort gives back a full melee on charge Melee kills, Handheld Supernova, and the Exotic pairs well with it, Converse Hold, were both nerfed. Otherwise, no Warlock melee has a one-hit kill potential with melee or grenade abilities. And that's just what I have time to comment on. You can't say that "each class is unique" while having two classes share abilities which the third class lacks. And no, Warlocks having abilities neither Hunters nor Titans have does not alleviate that.
