Yeah, I even made a whole thread about it after I spent so much time at the Azure Vault to get those trinkets recently. I am really passionate about this topic because it’s so easy for them to give us those better visuals which are already in the game but for some inexplicable reason they just don’t.
It was the same with Arcane Explosion/Arcane Missiles and Arcane Blast which were only ever updated for the first time in Legion (2016). Before that they had not been updated since Vanilla (12 years) and TBC (10 years) respectively.
