I ended up playing around with Moon Guard Robes and I quite like this!
Druidic Helmet of Second sight is a recolour of Tier 2. Spell Fencer's shoulderpads with Gloves of the Shadow's return look quite good together with the Belt of the Netherwalker. The last 2 are quest rewards from the Hunt for Illidan Stormrage. I used Kamui's Crystalline Staff of Wizardry for the weapon, though Void-Warped Oshu'gun Spellstaff is not a bad option either, and would make me look more druidy.
Except for the helm, these are part of the Dreadleather armour recolour (thought there are a chest and legs that can be used instead of the robe).
Think I'll stick with this for a while!
