You only need to click to run rep with about 20 Medallion of the Legion, to get new faction rep revered. Do to this, the Draenor flying can be expected soon.
Players may get some extra mounts and Garrison resources from the four rare elites, but it seems impractical to get lots of Medallion of the Legion. Luckily, Medallion of the Legion is tradable and also can be rewarded from the follower mission. So buying Medallion of the Legion from AH with wow gold to get rep is very easy.

Mounts in current expansion all ask rep exalted, so it is an imperative for mounts/pets junkers to do all reps exalted in Draenor. Medallion of the Legion will help you to run rep exalted fast.
