I wish! I did play priest back then but was a bit of a noob and didn’t set foot anywhere near CMs. If I had known, I would have pushed harder and tried to get that sweet gear and Phoenix mount too.
Now that I think about it, I think I may have the green version of that staff from rated PvP back then…not that it would go with this mog, but I may use it anyway because it’s rare in comparison.
I personally prefer the staff appearance of Aluneth. Not only does this staff whisper to you while you are questing out in the game world, But it also matches my current transmog perfectly!
I don’t have a favorite, I tend to swap around depending on the mog. I’m using Intensity from Wrath with my current outfit because it’s scary how close it matches it. With my mage I use the Legion appearances alot and the Pandaren inscription ones as well.
If you want something a bit simpler but that meshes well with certain transmog themes and works well for keeping the gnomes in line when they feel like expressing that they too should be paladins, I find that the Staff of Interrogation works well, as you can see here with one of mages:
If we are ignoring the artifact skins, my favorite for a mage type character is the Staff of the Grand Imperator from highmaul. It’s just a huge ball of glowing energy that fits a fire or arcane mage perfectly depending on mode color.
