Recycle means to reuse the same thing. As explained, the model is not being used or reused for Reforged at all, what we have is a completely different model made by a completely different company. I mean you can’t even say the HotS model is recycled from WoW or the cinematics, since they aren’t the same model at all.
Did you mean the design is a derivative of the Sylvanas concept in HOTS? I would even argue that there are too many things different to be derivative of that. To me, it’s a brand new take on a ‘Dark Ranger’ that has completely new bits like the face covering and the pointier hood and the complete lack of a cloak.
Honestly, this is the first time I’ve heard Sylvanas mentioned by name. I’ve seen comparisons to the Dark Ranger of WC3 or general WoW Dark Ranger, but not Sylvanas herself.
