I'm a bit confused why this was allowed to go on for so long and establish so much RP elements tied to it if it was inherently unapproved and disputed? This is a major retcon, some compromise should be possible to prevent undoing a year of work, eh?
To put it very simply: because people do not communicate these kinds of things. Unapproved edits are a very big running trend when it comes to the Vekimen, unfortunately. Not everyone has the time to look and spot-check everything (even Frost, despite what people think), and as a result things do slip by. This is why, when the topic came up recently, it received TONS of flak. Because it was publicly discussed and most likely saw countless creators and FMs (as
@Wes said was part of his decision in this involved multiple) finally speak up on it, it got overruled.
Retconning RP sucks, but this issue's avoidance could have come by simply communicating. Some people (such as myself) have opposed this part of the Vekimen for some time, with some despising other aspects. Most if not all of those people HAVE vocally opposed it in the past. The issue is that it kept boiling up and resurfacing, the tone kept changing, and things were joked about that clearly were taken seriously. This isn't some "flip of the wrist" thing that happened without reason: it is definitely unfortunate that people built RP on something that DID require input from other faction managers (such as those who voiced AGAINST the compatibility) and from the NTSE (such as the pheromones in their original state, though I believe they've been tuned down and still rose problems).
If there can be an alternative reached, awesome. But if not, because this RP was built upon a lack of communication and attempt to RP with the site in mind? Then I personally feel that the mistake was a large one and is just going to have to be dealt with. Rather than scream and fight about "muh RP", which is precisely why the people opposing these traits spoke up (because they feared for the RP of their site being harmed or their own stories being touched by these) to make it about the actual issues instead, the solution comes down to people being willing to try and figure out how to fix and solve the issues of this RP.
I still don't understand why unapproved edits get RPs built on them, but that's a discussion for a different thread. This thread does not need to be some whining fight, it needs to be discussion and attempts to find a solution instead of keep fighting.
Edit: And a brief reminder? If you just like the RP, then just keep doing it. The RP would be non-canon, but if you enjoy RP then you should just do it. If someone is willing to argue "RP first", they should lead by promoting the fact that they can still RP regardless of how this outcome rolls. It shouldn't change your plot and effort.
