Guardian of Ancient Kings visual effect looks like a ps1 character. I was so happy to see Shamans Ascendance forms get a visual update that I’m blown away paladins form got skipped. While they need a bunch of visuals updated, Guardian of Ancient Kings and Consecration are desperate to be brought up to speed and I hope its being worked on.
Honorable mention to Auras needing a complete rework. They are archaic, not noticeable, and I assume they rob power from other parts of the class. Beacons for Holy paladin are also out of date and don’t belong in modern wow. There is SO MUCH paladin aesthetic to work with that it seems impossible to not come up with a fun and modern solution to how Auras and beacons function. You could honestly remove both auras and beacons from the game completely and I bet no one would even notice.
