They are Hero Class from Warcraft 3. Lore wise they make absolutely the most sense to get and they've been teasing them every expansion since WOTLK. While Kor'kron and SI:7 have gotten jack shit in terms of lore and story, not to mention they do not exist as a class in the previous Warcraft games. Dark Ranger Cyndia is a dark ranger who wanders the Undercity. She has a patrol path that encompasses a large section of the city, including the Trade Quarter.

7 Mm, then there's heroes like the Tinker and the Dark Ranger that are brilliant when you know how to use them, but I'd say Tinker is the harder one to use properly as the Dark Ranger is fairly easy in terms of Silence. Other than that, it's mostly Black Arrows you'll be focusing on in the most common scenarios. Dark Rangers are level 72 - 73 elite Forsaken guards found at Vengeance Landing and Ghostblade Post in the Howling Fjord. Dark rangers are also found in other places on Azeroth such as the Undercity and the Forsaken High Command. Sylvanas vs Dark Ranger Tyrande vs Priestess of the Moon Muradin vs Mountain King For Sylvanas vs Dark Ranger, Sylvanas' spell animation is looping while the Dark Ranger's is nonlooping. Not sure if it's a bug or something. I simply didn't bother uploading an optimized regular Dark Ranger.

About the set:

This version of a Dark Ranger is based loosely upon Dark Ranger Clea in Undercity, whom we have included a picture of at the bottom of this article. Note that Clea does not wear any shoulderpads, although we have included a couple of fitting options for this armor slot anyway.

Head – Cowl of Defiance (Drops from Netherspite, in Karazhan at an 18% drop chance)
Shoulders – Mistshroud Shoulders (Drops from Ethereum Prisoner, in Blade’s Edge Mountains)
Back – Master’s Cloak (BoE world drop)
Chest – Tunic of Assassination (Drops from Pathaleon the Calculator, the final boss of The Mechanar. The drop chance is 13-14% in both Normal and Heroic modes)
Wrists – Nightfall Wristguards (Drops from Heroic Epoch Hunter in Old Hillsbrad Foothills. The drop chance is 20%)
Gloves – Handgrips of Assassination (Drops from Aeonus, in Normal and Heroic versions of The Black Morass. The drop chance is 15%)
Waist – Girdle of the Deathdealer (Drops from Heroic Aeonus in Black Morass. The drop chance is 15%)
Legs – Leggings of Assassination (Drops from Normal and Heroic Murmur in Shadow Labyrinth. The drop chance is 10%)
Feet – Shadowstep Striders (Drops from Heroic Harbinger Skyriss in Arcatraz. The drop chance is 26%)

Dual-Wielded One-Handed Sword – Widow Blade (BoE world drop)
Extras:

The following shoulders also fit the appearance rather well and provide a leather alternative to the above:
Shoulders – Shoulderpads of Assassination (Drops from Talon King Ikiss, in both Normal and Heroic modes of Sethekk Halls. The drop rate is between 12-14%)
