I've taken part in corpse hunting a bit, so I guess I'll add a little, though to be honest I've only been the one to look for the corpse- never the one to hide it or be important enough to be slayed and hidden (though the latter is an achievement I strive towards to one day have accomplished)
I will say, from the standpoint of -looking- for a corpse is not overly thrilling in my opinion. Initially there is a lot of excitement and this feeling of priority... though I feel like that quickly devolves into my character running around maps aimlessly by themselves after not finding the body a couple of days later. And to me that's -painfully- boring. But I do it because it is more often than not something my character would do. Even if you have a hunting buddy, which does significantly make the RP, well, -there-, it can get dull. Although I'm sure circumstances like who your character is, what they know, what skills they have, all impact the outcome- and my characters tend to be more RP so their practical skills can be limited.
I'm not in love with it, but I think it should definitely stay a thing. People can be resurrected but only if you have the body right there? It seems pretty natural villains would go and hide the bodies at least in some circumstances. Although I also agree kidnapping and interrogation, etc, would leave more room for actual RP at least with the victim and the kidnapper, and people could still go looking for the one that was taken. Though at this point kidnapping is, as far as I'm aware, done via some method of corpsing somebody and bringing them over somewhere to be raised again. Would be cool if we could subdue people and drag them off without killing them, as I think that's a little more realistic and less, well, bloody, but I don't know how that would be implemented.
Overall though, I think the system is flawed, but fine. It's gotten us this far, and I haven't heard about a drove of massive issues surrounding it because people tend to conduct themselves fine. But again, limited experience, and by the time I got to this thread there were -so- many responses that I mostly just skimmed through to be completely honest...
TDLR: Do I think corpse hiding should stay a thing? Yes. Would I be upset if there were changes made to said corpse hiding? Most likely not.
