As is the nature of role playing games, the rules are very often incomplete and open to interpretation. This can often spawn differences of opinion on answers and lead to lengthly comments over whether a particular point is correct or not.
When this happens moderators are prone to delete the comments and leave one of their own:
Don't argue in comments. Present your opinions in your answer.
I don't hold that against mods, they're following procedure; but I do find it frustrating. Posting two differing opinions in answers leaves no room for discussion on those opinions. It doesn't allow for anyone to point out why an answer might be flawed, except in your own answer.
Is this really the best policy? I'm not saying that comments is necessarily the best place for these discussions to occur, but I feel that valuable content is being lost because these comments are being deleted. Is there a better way we can handle this so that content isn't lost? Can we encourage users to place it in a better place where discussion can still continue and be publicly viewable in the correct context (i.e. linked to the question / answer they are discussing)?
