Update: The achievement has been hot-patched (December 9, 2014) to only require 1 exalted Draenor reputation, instead of 3. (It still displays a requirement of 3, but will be awarded when 1 reputation reaches exalted.)

Once earned, it unlocks the blueprints for all of your characters (although you will still need to purchase the blueprints on each individual character you want to build the level 3 Trading Post for).

Barracks Bodyguards do not count toward this achievement.

Although Nat Pagle reputation can be gained in Draenor, that reputation does not count toward this achievement.

6.0.3 Hotfixes: December 9

Trading Post: The Savage Friends achievement now only requires the character to become Exalted with 1 Draenor reputation (down from 3).

I just received this achieve today on Oct 22, 2014 while checking mail on my alts. Believe its yet another one of Blizzards bugs the comments say that you have to reach level 100 first. Also says its account wide achieve but I only have it on my 1 horde toon with the least amount of rep.
