FYI, this seems to just be an adjustment to the new level in the new patch. If you already have a Scion from the last patch, and take a new Scion up to 25 Zee-fever, nothing bad will come of it (you’ll still get one scion legacy for your next character).
However, as mentioned, it doesn’t seem that you need to do this to get that scion legacy if you already did it before the patch for your current character, if you don’t want to.
