The Golden Lotus

Gaining reputation with the Golden Lotus changed in Patch 5.4: Siege of Orgrimmar. When Garrosh Hellscream pushed Y'shaarj's heart into the waters surrounding Mogu'shan Palace, he changed the landscape and the Golden Lotus was hit hard. The remaining NPCs that offer daily quests have relocated to the Setting Sun Garrison.
The ways to gain reputation in 5.4 are:
.Daily quests, including Work Orders from the farm: Work Order: Golden Lotus I

.Killing mobs in the Vale of Eternal Blossoms, including the rares from One Many Army

.[item=94227], dropped by Zandalari mobs along the coastal areas of Pandaria.

If you so desire, feel free to purchase the [item=93215] to help with the grinding from Revered to Exalted for your main, or to help your alts if they plan to gain rep with the same faction.

Reaching Exalted will be offer The Might of Three
and after that you get The Final Power
which rewards a 489 epic neck:
[item=90592],[item=90593], [item=90594], [item=90595], [item=90596]

When you get this achievement, you must speak to [npc=59340] if you are alliance. He is located in Setting Sun Garrison. The quest he will give you will be the start to receive your epic neck piece. I wasnt finished with the dailies and i still was able to start the quest chain the same day i reached exalted.
