Warlords of Draenor introduces several new reputations, with rewards and quests to gain reputation. Unlike Mists of Pandaria, reputation rewards are mostly cosmetic or vanity items rather than gear that increases your character's power. The factions are laid out below. If you're looking for more detailed guides to any faction, check out our Warlords Guides
All but the two Ashran PvP Factions have pets, with all reputations having mounts added in the most recent build, and all feature a Tabard which is purely a vanity item. Most factions also have rare-quality trinkets that summon an NPC to temporarily fight for you, and flasks which offer a zone-specific damage boost as well. Frostwolf Orcs and Council of Exarchs also have defensive items without zone restrictions and Elixirs for their home zones.
The two factions tied to your Nivel
, the Sha'tari Defense and Laughing Skull, also have additional transmog gear. These factions have no quests associated with them, just killing mobs in level 100 areas!
