in case if someone have missed these NPCs.

I can't believe you can buy 3x Golden Lotus with just one Spirit of Harmony. Those herbs sell 300g each on my server, so one Mote of Harmony is worth 90g at the moment.
Just need a decent farm place for the motes. So far the best place I've found is in Krasarang Wilds ( http://www.wowhead.com/npc=57649 )
