I've just about completed my Cenarion Raiment set (only missing the boots), but the robes finally dropped so it looks complete nevertheless!
The Cloak of Unending Life from the AQ20 quests (made with the Idols, Scarabs, and drops in AQ20) matches it perfectly too. I don't have the best weapon for it (something like Dreambinder would probably be fitting), but it's quite fun using my Sulfuras with it, even if it does look a bit out of place.
I had a ton of fun healing a few randoms in the gear, so I may start doing that now to liven up my daily LFG (though if I get any of the ICC 5-mans I'd have to pop my proper gear back on).
I think this is one of my favourite tier sets - I love the leaves and twigs, and it just looks very much like something I'd imagine a druid would wear. If any tier set model were to be revived in Cataclysm or later, I would definitely hope it would be this one. The Cenarion Expedition tabard goes quite well with it all too, and the Guardian of Cenarius title just tops it off. Altogether it makes a really great druid set!
