Rank

In World of Warcraft
In World of Warcraft, rank can mean a few things:
 * 1) The relative effectiveness or level of a spell compared to a spell of the same type.
 * For example, comparing two ranks of the Priest spell, Lesser Heal:
 * Lesser Heal, Rank 2: Heal your target for 71 to 85.
 * Lesser Heal, Rank 3: Heal your target for 135 to 157.
 * (In Cataclysm, spell ranks will be removed, with spells instead scaling with levels like heirlooms do now.)
 * 1) The stepwise effectiveness of a talent in a talent tree. A talent with less than 2 ranks could be said to use only 1 rank, or no ranks at all.
 * 2) Your position (also known as Ranking) in the military hierarchy of your faction. See the Honor System (pre-2.0) page for details.
 * Also see PvP Ranks at the Official WoW site.
 * 1) Your position and assigned privileges within a guild hierarchy.

In Warcraft: Orcs & Humans
