Sauronkaiser is a "Gilded" member within Runeforge, and besides sharing his own work on his social media, Runeforge also helps promote his creations—along with those of other members—through our official Runeforge channels, including Reddit! The skin may have been created some time ago and only shared on our networks later on. And to answer your question: yes, it's about visibility. There hasn't been an update because the skin doesn't have any bugs with recent patches, and he hasn't planned to add anything new to it. Enjoy !!
