Classic Battles

To supplement the links under the "Criteria" (above), here are the faction/BG combos:

• 
  
• [faction=510] is the Horde faction of [zone=3358]
• 
  
• [faction=889] is the Horde faction of [zone=3277]
• 
  
• [faction=729] is the Horde faction of [zone=2597]
• 
  

This is a guild achievement, and gaining exalted reputations with these factions will also count towards larger rep achievements for your guild (maxing out at United Nations, which unlocks guild access to purchase the battle pet [item=63138]).

Personally getting these three reputations to exalted will give you the PVP rep achievement The Conqueror, in addition to counting towards your larger rep counts (maxing out at 60 Exalted Reputations, rewarding the title "<name> the Beloved").

Yes it is, It is under the guild tab. It is poorly explained though... It is not a single person that shall all of them. when some1 in the guild got one of them that criteria is filled. if the guilds combined members have them all, then you suceed.
