Hi all, I am wasting my interrupt on enemys who are casting unkickable spells. The shield on the blizzard default isn't reskinned or showing for me. How can I change this?

Sorry for taking a while to respond, must have missed the notification for this.

There's no setting that toggles this behaviour, there should be a shield that shows up. And when I tested it just now to double check it does show. There was an issue with this in the TBC/Wrath versions prior to v416, so I recommend you check what version the addon is and update if needed.
