Legendaries need to stay unique?
There is always a lot of people in LA with legendaries. My guild have a lot of people with legendaries. There was always 1 or 2 persons with legendaries when I used to run dungeons.
The only reason I don’t have a legendary is because I only play necro and the only legendary I like is Twilight (I got Dusk but sold it for 800g).
So nope, legendaries aren’t unique, just really expensive (if every single player would really work for one, everyone would have a legendarie).
And no, even if you can craft a precursor, people will still pay a lot for them so if this is an attempt to lower the prices well, is a lame attempt and isn’t going to work.
