Another faction that has proven to be entertaining is the Order of the Cloud Serpent. The idea here is pretty much the same as the Netherwing faction in Burning Crusade, but you really couldn't have a game with a Chinese theme without having the chance to be able to ride a cloud serpent as a mount or get one as a pet. The rewards here are purely vanity, mostly mounts and a few recipes, but the quests that require you to play with your serpent (or clean up after it) have also proven to be a nice respite from the grind. If you aren't up for a what may seem like a never-ending grind, hunt a few onyx eggs to make it go by faster.
The last faction that has kept me a little too engrossed is the Anglers. As the name suggests, these fisher folk offer quests requiring you to do things in the surrounding waters. The group is headed by the legendary fisherman of Azeroth, Nat Pagle, and doing these daily quests will also get you vanity items. If you are like me and spent a lot of your idle time in-game listening for the familiar splash of a fish grabbing your lure, then you may have a few similar items to the rewards that the Anglers are offering. But it's just another fun faction that alleviates the seriousness of the heavy storyline going on with the main factions in the game.
It is nice to see Blizzard trying to offer a bit more personality in its daily-grind quest design.
