This question was asked by Phyx on the forums today. His question got me thinking how I liked seeing my priest. Of course I only started playing her in BC really, so I can only think back that amount of time.
I do remember that at a certain point I had a specific set with the gladiator hood that had the blue halo around it that I absolutely loved.
When I get home I'll go play with the WoW Modelviewer a bit, and I'll see if I can get some screenshots taken of what she looked like back then.
How about you, what do you feel looked best on your character?
