@Tawg of course there is problems with RAW, but if you dislike the concept then why comment?

I'm glad that we agree that there is no support for direct lines, this means I have been playing it the right way.
The premise of your original question was not "How does this work RAW". Although re-reading it, it could be fairly clearly assessed as you asking for what would be considered "RAW". So I answered your question, I just asserted that it was my preference. And while you acknowledged and thanked me for my reply, you made the statement that you were looking for an answer that is as written,
rather, presumably, than my answer. I assumed this meant you supported direct lines, as you had not presented a solid stance as of yet, which I believe then caused confusion between my second post and your third. Because we were both suggesting that moving around any obstacle was correct, and assuming the other was in favor of direct lines. Which makes both of us questioning the 2nd definition more understandable.
I merely added a bit more lengthy comment about how the definition of the word itself can still be taken in more than one way, because it is not clear even looking at it. And explained that I don't believe attempting to explain things strictly by what is written can be achieved in many cases. Sometimes English simply isn't used correctly enough and it leaves more than one possibility open, which would (In a wishful world) be what FAQs/Erratas would be for.
It's just that the "RAW" idea is not flawed in execution as much as in ideals IMO. It's attempting to create a binding ruling that is "Supreme" over all others. But the goal shouldn't be to bind, but to play and understand the game. I mean, with tournaments/game-stores having agreed on rules that everyone understands is clearly great, but it shouldn't stop people from disobeying rules that clearly make no sense. (An example from
40k would be that a Necron Praetorian unit can take a transport, but are a Jump Unit, which are not allowed in transports. RAW says they can take the transport but never
get in the transport. That is clearly non-sense.) So I just dislike very strongly the idea that one way to read the rules is correct.
But I like to understand, and debating or disagreeing over rules only strengthens arguments, and potentially illuminates points of fact that lead to a more concise way to see the rules. Some games don't need as much debate (M:tG, Warmahordes often is fairly clear, etc.), but I think it's always a worthwhile venture. I just don't support the notion that a single way to play the game is the only way to play it.
Plus we simply misunderstood each others stance on the subject, when actually we agree. But, again, if someone insisted that it could only be in direct lines, and that we both agreed to play in such a way, I would not argue with that. And I don't think the rules are concise enough to say that they are incorrect. So I say mine is preference, but it is also "RAW", as "RAW" as the alternative may be.
