She's a Destruction Warlock, though I've recently been trying out Affliction I think my heart will always belong to Destro.

Illdriesta at Level 14

Level 41 - Gosh I loved those Black Velvet Robes

Level 51 and all colour co-ordinated, the Whitemanes Chapeau was with me for a long time

Level 55 - These robes started off great, but when I couldn't replace them for 10 levels I learnt to hate them. Also the Guild tabard stopped matching my gear :o(

Level 70 and you can see here that the Blizzard Crew took some feedback about making gear sets match after WotLK

Level 77 and the gear looks just like a recoloured version of my Level 70 gear

Level 81 and I'm in guild provided craftables with questing accessories.

Level 83 - item level 303 which is mostly a Deathsilk Tailoring set, looking again like a dark version of the Level 81 gear. Note me cycling through tabards for Reputation.

And finally just after Level 85 (iLvl 326) everything changes! Intellect weapons replacing staves, Shadowflame Robes with mostly Fireweave accessories and a Ramkahen tabard.
