Hello, Yes that armor will become an ornament set. What will happen to the armor if you still have it hasn't been released yet.
Eververse sets are becoming ornaments and everything is changing on armor. I would just simply use the solstice set if you’ve completed it or a max 750 set as a place holder till you get a 2.0 you like. Then you can apply the ornaments to make it like the set you like right now
