I think that it would be problematic.
The knowledge of your map knowledge might cause others to assume that what you are saying is related to what you know.
Our cruel but fair hostess have to make a call, my personal opinion is something like this:
Vote - no.
Comments - theoretically possible... sort of. If you are overly careful with your words and only talk in abstract and/or general terms. But the bar has to be really high here.
I and many others have alot of time and effort invested in this project. And alot of the value is in the fact that the map is a mystery and even the slightest glimpse of knowledge could ruin the fun for some.
I know that some maps I have played when I would add archery to barbs, carefully zooming in and changing fov to not see and spoil anything I have forgotten to take of the headset and when I heard the horse sound a big chunk of fun is taken away.
I might be more sensitive than others, but others could also be even more picky... I have seen posts by Lain where he asks others to make him a save with archery added, just the eliminate the possibility for this random mishap.
