Suggestion
Add a regex that checks for a Wowhead article URL (e.g. https://www.wowhead.com/news/foo-numbers) and warns the user if the URL is linking to the comments section (#comments at the end) or to a specific comment (a #p followed by numbers, e.g. #p981371839413), telling the user to fix the URL by erasing its tail-end.
It should be around here, assuming you're on PC and using New Reddit
Quick example RegEx I've cooked quickly on Regexr.com:
wowhead.com/news/.*(#comments|#p\d*)
I am not sure if that covers all the edge-cases for Wowhead articles, though.
Reasoning
First: It is terrible to open a Wowhead artcile and having to scroll up to actually read the article. I have yet to see a where the comment's content is the actual post's subject rather than the article's content.
Second: It can mislead people into thinking the comment is the actual article.
