Models Standing on Shadow-Generating Terrain, and Reciprocal Line of Sight

[Kharnage]

So, according to Core Rules, because the "model standing on terrain that is casting a Shadow ignores that terrain (and its Shadow) if any single sight line drawn between the two objects passes through 1" or less of that terrain.", LoS can be one-way. This theoretically lines up with concealing terrain rules, where being in something lets you ignore something that models outside of the terrain can't ignore. The problem is, when no one has the room to join you in that terrain, and the feature you get to enjoy is being able to affect models or take attacks, this devolves, in my opinion, into a huge NPE. Observe.

The Rock she's standing on is Ht 2. Nekima engages all of these models. If they're close enough, they can even be splashed on if she somehow takes damage (cuz it won't be from these models). However, none of them can see her in return. She's functionally immune to melee attacks while being able to chop all these people to bits at her leisure.
This is, I would *hope*, an unintended consequence of the rules listed below.

I beseech the powers that be, please change this. This isn't fun, or good, or realistic, and it should be changed. Or 'clarified', however you want to think about it.

Please listen to this fine gentlemen who does know what he's talking about. Non reciprocal LoS is an unnecessary nightmare in game and affects new players the worst.

I agree the above situation is not fun, and should be avoided. 

First point - the players at the table should define terrain. Ht 2 and 3 terrain that is less than 100mm in diameter probably shouldn't get to be stood on. 

And if it exists, then you shouldn't really send ht 2 models within 2" of it. 

(I'd argue it is pretty realistic, if someone is standing on something above my head, I can't see them to hit them with a sword if they want to be avoided, but they can easily get themselves to be able to see me when they want to. )

 

I view the above situation as a situation that the rules allow, but the players shouldn't. Just like ht 8 sniper towers or 24"long river pieces that count as 1 piece, or spaces only incorporeal models can reach.

So whilst the above situation is allowed in the rules, its the most extreme situation possible of this instance, and to get to it, the players need to rule the terrain can do that.

I don't see this as an argument that non reciprocal LOS is a problem, but rather models shouldn't be allowed to stand on terrain that no one else can stand on that is just the right height to screw up a crew (Make this a ht 3 rock and it gets a lot less of an issue in the above example, (but causes the same issue if you are facing lots of ht 3) since she can no longer bleed on them, and make it ht 4 and Nekima can no longer hit ht 2 people even though she can see them).

I can certainly make a bunch of other situations that would lead to a similar outcome of Nekima is engaging a group of models that can't engage her back without it being a reciprocal LOS issue. But most of them would be caused by me deliberately using the game rules to create such a situation.
