Right so I can see now that this is part of a much wider discussion/point of confusion and wanted to elaborate a bit:
Please note that Customer Support shouldn’t be used as a source of truth for drop-rates or other internal specifics. As such, please don’t make tickets for this, or treat information provided in ticket replies as official announcements (especially if it conflicts with other publicly available information, or where no public information exists).
I didn’t intend to provide any new information, but rather point out the already published details regarding the X-45 Heartbreaker mount (which as far as I know is still correct, but if it has indeed changed, Customer Support should again not be the source of any such announcement).
Part of the confusion here also seems to stem from this being conflated with a new mount, Love Witch’s Sweeper, which may work differently.
As a general point it’s typically up to the community at large to collaborate and discover how these things work but if there is a need for clarification or a big change is coming, keep an eye out for official announcements (typically via Community Managers, or the website news/blog).
