Now, I'm not going to start a rollback war and I'm not here to criticize this user's reasoning over why the rollback was needed, rather, to make sure that what I did to edit the question title/body was actually unnecessary.
I had edited the question because the question title did indeed contain a spoiler (for a game that hasn't been out for a year yet) as the first commenter mentions. I explained my reasoning for the changes in a comment:
The game hasn't been out for even a year yet. Even then, spoilers are not constricted to a time basis. Given that, the title would still be a spoiler to anyone happening across it. I can see why the body would not need to be changed, but I simply did it while I was already editing the title.
- I've been to other SE sites that state that spoilers are not necessarily restricted to a certain time window. There can always be someone who hasn't enjoyed the experience that could have it spoiled and that should be protected (I don't see why it should be different in this case, especially with a relativity "new" game).
- I can't remember the related meta post off the top of my head, but another reason I edited the title was to get rid of the "- The Witcher 3" part.
- I don't really see any reason that adding spoiler markup in the body actually hurt the post. Although I am by far the most lenient on this point, as they likely didn't help the post nearly as much as the title edits. I just did it while I was there. (the linked possible duplicate in the comments answers part of this, and is definitely not a duplicate of this post as a whole)
I'm curious as to the opinion of the community, for future reference of my editing (and I suppose for reference to the post in question as well).
