Why should we completely disregard the FAQ's?
Saying they're house rules is a load of BUNK. Even if they are house rules at minimum their amendments and clarifications that the Designers THEMSELVES use when balancing (arguably) and playing the game, as such they hold weight on whether we go one way or another with a rule that is sitting on the fence.
Now I'm all for "modding" the game so to speak with custom scenarios, lists that aren't official (see Eo's harlie list or an chaos army with terminator troops) but these things require discussion and preparation and as such are special occasion's, if I walk over to a gaming table on a Thursday night and you roughly demand that falchions offer +2 attacks because the FAQ is "clearly" bunk then Im either going to want my own ignore the FAQ, or I'm not going to play you. Why? because my free time is precious and I don't want to spend it playing against selfish fools who think their own view is the only one that matters.
