Why are people so bad with the rules for 40K? It seems like a day does not go by where some blog publishes a post with an incorrect rule in it. Sometimes these mistakes are just little parts of battle report recaps or tactica but sometimes they are the whole basis for the post. Anytime I see this I try to leave a comment so that these things do not keep propagating through the player base. Sometimes people come back and tell me that I am wrong. Often when they do this they are correct or the rule is one of the great gray areas that haunt the system where they are just vague or make no sense.
Do you still encounter players who claim that if you charge into an ongoing combat the opponents models cannot attack the new chargers? I remember that happening to me during a small tournament not long after 5th edition so I discussed it with my opponent about it even though I was the one doing the charging. I swear that this is something that people saw in rumors and propagated since the actually rule is not crystal clear. Of course if you applied the logic that gets to that point to the rule properly you would end up with charging unit not being able to attack in close combat since they were also not engaged at the beginning of the assault.
You look at the Adepticon FAQ which is longer than the basic rulebook. It does include all the codices but still GW should being doing a better job of writing clear rules. You look at a site like warseer and see 15,000 topics and 220,000 thousand posts in the rules area. Sure many of these repeat every few months but come can we not read the rules or are they just overly complicated and not clear.
Can you look at the rules for the hive guard Impaler cannon and say for certain whether those rules are limiting covers saves the target can get or just trying to say how to treat cover for direct fire weapons that do not require LOS.
I look at the competition Blood Bowl rulebook which is like 40 pages with a 1 page FAQ. It is pretty clear because people have put in over 2 years of unpaid fulltime work into getting it into a clear, concise, and compact. The biggest problem with that rule set is that both the Block actions and Blitz actions have a Block in them and if their was an addition name for hitting people things could be clearer since many skills do not work for both block parts of blitz or block actions.
