The Warlock is the Force Commander's thinner brother who, due to some kind of social anxiety problem, always wears a mask. The Force Commander and the Warlock are similar is many ways. Both have high-damage weapon upgrades, both are meant to be used in a heavily offensive strategy, and both can defend themselves with shield bubbles. The Warlock has two inherent abilities. One is Fleet Of Foot, which is not a Warlock-exclusive ability. It is great to have as it helps the Warlock close the distance against enemy ranged units, like Tactical Marines. The Warlock also has Desturctor, a moderate-damage ranged attack which becomes more powerful as you level. Its damage is too low to threaten heavy infantry, but light infantry take moderate damage.
The Warlock has three strong weapon options. The first is the Immolater, a moderately effective weapon which gives the Immolate ability, an area-of-effect flame attack which is good against low-quality infantry. The Merciless Witchblade has no special ability, but it is powerful and it drains energy with each hit, making it great against enemy heroes using a shield. Finally there is the Witchblade Of Kurnous, which is a strong blade that has the Ethereal Slash ability. This ability is a nasty PBAOE attack with knockback, and is capable of doing heavy damage to any infantry. All three options are good, but the Immolater does seem a little weak compared to the Witchblade Of Kurnous.
All three of the Warlock's armor Wargears are strong. The Champion's Robe grants the Psychic Shield ability, which causes incoming damage to drain from energy instead of health while active, and also gives a decent health boost. The Cloak Of Shadows is more subtle, as it provides a small health increase and the Conceal ability, which will Conceal not only the Warlock but also nearby friendly units. Last is the Providence armor, which gives a major health boost and the Providence ability. This ability charges from damage taken and once activated it renders the Warlock completely invulnerable for a short time, and also increases damage and regeneration. It is a very powerful ability, but since charging it requires damage, you have to be careful.
The utility options aren't that exciting. The Channeling Runes simply gives the Warlock an ability which will regenerate health and energy over time. Warp Throw is probably the best utility option as it grants a special ability that literally throws enemy units in a set direction. The knockback effect from this is extremely strong, it is great for use against squads that have to deploy their weapons. Finally there is the Heart Of Darkness, which gives the Warlock an ability that adds 80 energy when used. This is good with the Champion's Robe, as it helps keep the shield up longer.
