Yeah this and de law of numbersI suspect that GW doesn't have people whose job is to read the rules that don't already know what the intention is, that is why things are so often unclear. If you know what the intention is and then read something it is much harder to see that the rules can easily be read in a different way.
When 10000 different people read the rules they may come up with more if just 10 people read them, also never forget there is a large Part of the community who WANT exploits, so they search them
