I have been thinking lately about in-game things which self-respecting Druids, or those with a lot of time, may have. Now of course some 6k GearScore and full Tier 10.x is a good start, but what about flavour items?
Swift Flight Form achievement
Now any Druid with 5k gold can train Swift Flight Form, that's not so special. Back in the day the only way to get this was to undertake a complex and fun quest chain, ending in facing down the Raven Lord Anzu. To summon him you got an Essence-Infused Moonstone and once you had defeated him and gained Swift Flight, you got the stone back again. When they added the form to the trainer, they added the Swift Flight Form Feat of Strength to prove you really did it.
As an epic and fun class specific quest chain, you really owe it to yourself and your Druid brethren to do this.
Reins of the Raven Lord is the Feat of Strength you get if you defeat Anzu in Sethekk Halls and are lucky enough to get the mount to drop. If he doesn't drop it while you are on the Swift Flight Form quest, you can re-summon him with the Essence-Infused Moonstone once per day in Heroic Sethekk Halls. Unfortunately the drop rate is 1.6% on Wowhead which potentially means a lot of grinding. However only Druids get to summon Anzu at all, so any other class with the mount is either very lucky or have a willing Druid to help them grind it.
Still, the mount is actually the model of Anzu and thus you have actually enslaved and are riding the Raven Lord himself, as well as saving the Emerald Dream. As a symbol of a true Druid, this takes some beating.
Guardian of Cenarius
The Cenarion Circle and Cenarion Expedition. They don't have any rep-sharing policies, but get to exalted with both and the title of Guardian of Cenarius is yours.
Who wouldn't want to be a guardian of the patron god of Druids?
Certainly if you have time on your hands, these achievements are a worthy way of showing your love of the Druid class.
Any other suggestions? Any other classes want to put up a similar list for themselves?
