Ranger (Warcraft III)

Rangers were originally meant to be a hero unit of the Human Alliance. They were described as such:
 * These fearless Half-Elven women are masters of survival and wilderness exploration. Trained to hunt down renegade Orcs and Trolls in the wildlands of both Azeroth and Lordaeron, the Rangers are a force to be reckoned with. Being Half-Elven, the Rangers are often avoided by members of the High Elven stock. However, these crafty females make their home in the wilds and seldom feel the need for the distractions of camaraderie. Rangers are expert marksmen with the longbow and carry specially weighted bows and magically enhanced arrows.

Rangers were eventually cancelled as a hero unit. Most of their abilities were given to the Priestess of the Moon instead, and their model was reused for the in-game appearances of Sylvanas Windrunner and Jennalla Deemspring. Shandris Feathermoon uses a night elf version of the Ranger. When the The Frozen Throne expansion was released, Cold Arrows was given to Naga Sea Witches, renamed to Frost Arrows and given a new icon.

Trivia

 * Among the possible random hero names was "Somand Wayfinder".
 * This became one of the random hero names for the Dark Ranger. It's likely that all of the Dark Ranger random hero names were originally meant for the Ranger.
