I finally earned Honor Level 50 this weekend and unlocked the green tint of the Fallen to Nightmare skin (the Ursoc-esque series) for my bear, which I had been looking forward to for a really long time.
I was somewhat disappointed to see that it seems to have changed a little. While it still has the same shape and green outline, the spikes are no longer pure green - instead, they seem yellow-orange with a green glow over them. It’s more noticeable in some lightings than in others, but even in a neutral lighting you can see it.
You can notice the difference on the Wowhead page about the Legion artifact appearances for the Claws of Ursoc as well. The static image still has the old (very green) look, but the model viewer has the changed spikes.
I think the teal one may have been subtly changed as well (I don’t recall the spikes having a pink-ish reddish tinge).
I was wondering if this was an intentional change (“adding some depth” or whatever) or if this is a bug with the interaction of how the effects work together. Personally, I did like the pure green a lot more - the new look just looks messy to me.
