Hey everyone, I have seen many different spots for farming Lovely Charms and did not see this particular one when I searched the forums. It requires the Daily quest : Unleashed Spirits to do, which is located in the Vale of Eternal Blossoms for the Golden Lotus faction. The quest itself has you killing, you guessed it, packs of Unleashed Spirits
These are shared tagged, non-lootable npcs, giving credit for the kill and the charm as long as you do damage to them. I myself stumbled upon it when i picked up the lovely charm kit, and then proceeded to do my dailies.
30 mins of killing and I got around ~135 lovely charms. This farming method removes the competition, merely because you don't have to compete. As long as you're there, doing damage, the charms will come to you.
The only bad side, is that it IS a random daily.
I didn't think this was intended by blizzard, if I did my math right, you could potentially get 270 tokens in around 10 hrs, which if I read the other spots guides correctly, this is extremely fast in comparison.
