The Brawl'gar Arena faction is responsible for keeping track of players' progress in Orgrimmar's Brawl'gar Arena - a place where players can test their own prowess against a number of bosses. Gaining reputation with your local Brawlers Guild is more akin to Pandaria's friendship system than to a faction: there are eight ranks in this system, each one worth 1,000 reputation. Reputation gains happen only in the Brawl'gar Arena, where players gain one rank for every four victories in the arena.

In terms of rewards, the Brawlers offer little beyond achievements and arena-only consumables. Clock'em, a Jeeves-lookalike with boxing gloves, is available to players of Rank 4 and up. There is also Brawler's Razor Claws, which requires Rank 8.
