[Meta] This sub needs a "Rule 5" like some other gaming subs. "Rule 5: if you post a screenshot, your post needs to include a comment telling us what we're looking at."

WoW is already very daunting to newbies and outsiders, and even as a veteran of multiple expansions, I see image posts on this sub every day with vague titles with the top comment "I don't get it."New rule: post a screenshot, post an explanation.Thoughts?
