Recently, I stumbled across a brilliant series of blog posts written by Vallen of Feral Aggression.
The posts are titled “Pimp Your Druid” and go into detail on how to obtain rare and unique mounts, items and shirts for your Druid. All of the guides are well written and contain helpful pictures and advice.
The series is as follows:
Pimp Your Druid – Sulfuras, Hand of Ragnaros
Pimp Your Druid – Reins of the Raven Lord
Pimp Your Druid – Swift Razzashi Raptor
Pimp Your Druid – Swift Zulian Tiger
Pimp Your Druid – Fiery Warhorse Reins
Pimp Your Druid – Swift White Hawkstrider
Pimp Your Druid – Reins of the Blue Proto-Drake
Personally, I have only obtained one of these, The Reins of the Raven Lord. This iconic Druid mount only took me one week (7 days) of farming and to this extent I was quite lucky. Doing circles around Dalaran has never been any more fun.
Good luck with your own farming!
