Prior to patch 2.01, you had to improve your Reputation with the Arathi Basin faction to make yourself eligible for rare and epic equipment rewards, as well some consumable items that can only be used in battlegrounds. Though some of the Highlander and Defiler factions sell items with different names and artwork, their bonuses and equip effects are identical. The old system is listed below for those interested, but to obtain the rewards, you must use the new system described above.
