How are "intervening models" relevant to game play? Primal p.43 defines what an intervening model, but doesn't explain why it is important. The only reference to it is under the four requirements for Line of Sight on the same page, but it seems unnecessary to that section.
"3. The line must not pass over the base of an intervening model that has a base size equal to or larger than Model B."
It seems like "an intervening model" could simply be replaced with "any model" and still maintain the exact same effect. Why the definition? Is it significant to anything else? I can see it's significance for Slam attacks, but is there something else I'm missing?
I thought I read a line in the rules about intervening models sometimes having significance to shooting, but I didn't note the page of that reference and never ran across anything that suggests an intervening model is at all significant to shooting unless EVERY line from Model A to Model B crossing the base of the intervening model... in other words the target is completely behind the intervening model.
