I'd agree, except that a few things also are considered official lore. Like that you can tell from a Pale Masters skin that he is a Pale Master. Or how you can swap the skeletal arm for other things with some extra stuff. I mean, I could be wrong, but at least the former should be posted somewhere. I mean, it's basically a rule, except that it isn't written down somewhere anyone has to or even needs to check. If something like that was stickied separately, ok, but not having it written anywhere and just assuming people know it is pretty careless in my opinion. Of course, I might be wrong, and it is written down somewhere, in which case it shouldn't be difficult to find it and give me a link, right?
Oops, just noticed the thread I was thinking about actually was the one started by Letum, and then was answered by Dead, after the Q&A was apparently discontinued. Here's the link. It moved to the second page of GenDis.
