No offense taken.
And I donīt want to redo the rules, but my line of interpretation may simply be another one.
I want to give you my line of reasoning, perhaps youīll find something that makes it clearer or gives a part of insight why I deduced this view.
And perhaps you see that itīs not totally invalid.
And I donīt want to be offensive by sticking to my point of view either. And I do not want to tell a rule untrue because it doesnīt fit my interpretation or liking. I just have another opinion and think this is also covered by the rules. (As naturally yours is too, even if I think that the part under 6.1 is more a filler in the sentence than a fix ruling - it is valid in itīs way)
And yes Iīm from another country and some other interpretations may differ through the translating. Or I canīt get it clearly out because of my lacking language skills.
So, what I tried is to go from the most basic rules - the definition of LOS - to the special rulings on specific actions. This leads me pretty directly to 6.2.7 where the action in question is defined and described..
Because 6.1 refers to move actions and spotting isnīt a kind of move action, I donīt give this part that much credit that you do.
Further spotting is under the general section 6.2 which actually makes it to an attack action - and again not a move action of another section.
Thatīs why I refer to 1.3 and 6.2.7 only and not to 6.1 in the middle.
Besides that the sentence under section 6.1 can be read in another way. Just another kind of pronounciation of parts - and perhaps I do it only because for me english is a foreign language - lets the sentence look like a listing which changes the outcome:
"However, if a figure simply wants to
1- turn around,
2- to fire at,
3- or Spot a model behind it,
it must use an Action to do so."
It can be read that the listed actions all cost an action; to be simply an enumeration of actions worth a full action.
And each of the listed actions is separated with a comma.
It explicitly doesnīt say "to turn around to fire at - to turn around to spot a model".
But your not accounting for 6.1 which clearly states this, and noware in 6.2.7 does it state you dont have to do this.
--> And again thatīs why I donīt see that itīs īclearly stated that you have to turn aroundī for spotting only.
