3. RAW is a myth.
This is one of the dirty little secrets of the board. The Most Holy RAW is invoked continuously by those who want to give their arguments the veneer of officiality. The problem is, RAW is generally applied not as "The Rules as Written," but rather as "The Rules As I Interpret Them And You Can't Prove I'm Wrong, Nyeah." The RAITAYCPIWN. Not quite as catchy an acronym, granted, but that's what it boils down to.
This game cannot be played without interpretation and the judicious application of common sense. Try to play the game strictly and exclusively by the rules as written, and you have an unplayable game.
Using "RAW" as a defense is similarly meaningless--particularly when your defense rests on interpretation. If you're going to claim that your build is RAW, you'd better be able to make sure that the rules specifically uphold your claim...not simply that they're sort of vague and COULD be interpreted in such a way as to not FORBID your claim.
This becomes particularly important when your claim is especially controversial.
Yes, builds should adhere to the rules as written. Yes, any exceptions to that should be noted. But the RAW as some sort of entity unto itself, capable of rendering a build immune to criticism, is not a useful construction, and causes more problems than it solves.
