Though I don't believe that there will be a necron FAQ any time soon, it does amuse me that GWS fans trust the rules writers so little that they expect an FAQ to clarify problems only 1 month after the release.
In my opinion, it would be nice if there had to be new codices released before there are problems with a codex just released. However, I remember when I first read the newcrondex and though some of the things were written a little bit ambiguously. I think if a rule appears ambiguous to a fan upon the first read, they should take that rule into question. I also always wonder if some things are lost in translation because I'm American, but I would like to think that it's not a problem.
