If there was data to show this was a massive dropping off point for newer players, it definitely would have been better to pre-face the question in the blog with that data to explain to players why we are polling it. Or if the data was there to provide, it may have been deemed to fall under the "new player experience changes" blog that we put out awhile back which discusses not polling those types of changes (examples of changes we've done includes Adventure Paths, Tutorial Island changes, and Login Screen changes).
I believe the scrum that wanted to poll it had good intentions and genuinely was curious as to what the community had to say about it rather than this being lumped with Underground Pass changes (given the scrum in OSRS that polled this is not the same scrum that polled Underground Pass changes). As far as I'm aware, now that the poll has failed, there are currently no plans to touch that skeleton's combat level and the feedback regarding that particular poll question has been passed to the particular scrum.
Hope this helps!
