So, I think a large part people seem to be missing when it comes to "playing by intent", is that the models physical location isn't something left in limbo, or blatantly left in the incorrect spot and I'm just magically declaring it is where I want it to be. Whenever it comes up for me, I've asked my opponent to help me find a spot for the model to be placed where we could both agree the intent of my move was the final physical location of the model. I choose to activate a model and communicate with my opponent about the intent of my movement. Then, using my opponents assistance, I move the model to a physical location that we can both agree fulfills my intent. This leads to a meaningful discussion with my opponent, where they may tell me I need to nudge my model a few mm back or forward from where I though it should go. We both agree on the placement and we roll dice. There is no opportunity to later "cheat" by saying the second model has LoF, not only because we agreed or it was intended, but because working together, we placed my model in a spot that we agreed did not physically have LoF to the second model. And sometimes, if models are on an angle, or the pie slicing is awkward, the line is so close that this just isn't possible, even though it may technically be mathematically possible, it is not practically possible to find a location, so we let the active player decide if he wants to see both or neither. And when it comes to saving time and the erroneous claim that people will speed up by just deciding to take the risk of multiple AROs or not, I think this is complete crap. If that spot clearly exists and you require me to place my model in that exact spot with no help or agreement of intent from you, I guarantee you I WILL find that spot. Because making sure my decisions are executed the way I intend for them to be is more important to me than fulfilling your desire to watch me make a fat fingered mistake. So I'll break out multiple laser pointers and you'll just have to sit there and wait for me to be completely happy with my position for every move of every model of every order and our game will either take 5 hours, or if we're at a tournament we'll only finish a single turn. Or we can play the game together, have fun, and be done in a reasonable amount of time where no one thinks the other is a dick.
