Raise your reputation with the areas listed below.
Title Reward: <Name> the Insane
As of 5.0.4 this achievement requires all reputations simultaneously, while achievable, blizzard has confirmed this as a bug and it may be worth holding off on the bloodsail/goblin rep's until this is fixed.
Alternativly, you can get honored with bloodsail and grind tanaris pirates/barrens pirates for the rep.
/run AddTrackedAchievement(2336) to track achievement progress.*Note, apparently the quest achievement progress resets on a server restart, so if you were to get both within the week + pray for no restarts you would get it. I cannot confirm this though.Good Luck!
