I also remember them saying that the person meant to work on the issue had been changed to a more urgent bug fix prior to the Q&A. No clue if they have gone back to working on this by now.
Also there was the information that unless a longterm fix would be found, no more weapons like Dawnbringer would be added. I forgot if that meant Soulforge weapons in general or only mythic weapons like Dawnbringer.
Also yes, apparently the devs had gotten complains about Runic Blade before DB existed.
