Hi all,
Since the prepatch Hammer of the Righteous doesn’t show its yellow trail animation anymore on my human paladin (male). I tested it on my lightforged draenei female and there the animation works correctly, showing the yellow trail.
Looks like the bug is connected to the race you play. Hopefully this can get fixed soon because the animation is way less satisfying without the beautiful yellow trail (that gets bigger and brighter the longer your weapon is!)
