So it's becoming more of a... not quite an issue, in most cases, but an unavoidable point of contention amongst members (active members) of the wiki on what is a weakness (a specific circumstance in which a character cannot readily overcome) and what is common knowledge (a bullet to the head makes you dead).
Case in point, the pillar of the DCEU itself, Superman (since he's the most central character so far) is a major point that everyone has their own reservations on. His weaknesses, and the weaknesses of every character, race, etc. is what will be discussed on this forum thread.
With this format, we'll get feedback from the general community on what shoupd and should not be considered a weakness in an overall unanimous concensus from everyone who visits this wiki.
Then, we will update the articles :)
(No such thing as a bad idea [unless it's an actual bad idea])
