Mag'har of Draenor

Being exalted with Mag'har, Timbermaw Hold, and Sporeggar will give the title "(Name) the Diplomat."

It's really easy to get exalted with these people. I went Neutral to Exalted in 6-7 hours of just farming the obsidian war beads, those were real crucial to getting exalted. A handy macro that I used which helped me turn in items faster, was this one:
/script SelectGossipAvailableQuest(1)
/script CompleteQuest()
/script GetQuestReward()
Copy and paste that to a macro and bind it to a key. (Note: You will have to keep pressing the npc you are turning in the warbeads to after you turn one stack of 10 in each time.). Good luck everyone on hitting exalted, I personally did it for the tabard/mounts. I did this with my fury warrior, and just pulled mass amount of ogres until I had enough beads to getting exalted. Should be really easy if you have an AOE class as the person you want to hit exalted. Good luck!
