So it would be fine if it's the hand? The underarm? The whole arm? When do we reach the point for when it's plausible and not immersion breaking to kill 30 models hiding completely out of Line of Sight?
If your point is to demonstrate that the entire principle of Line of Sight in 40k as written is stupid, then I agree with you.
It doesn't change the fact that claiming visibility to 30 models on the basis of a stray bit of cloth or an upraised sword is unnecessarily obnoxious. If anything, it makes it even more stark. You can already wipe the unit by just squeaking ONE torso or limb into view; do you really need to insist that a superfluous bit of cloak flapping in the breeze is a viable target too? I guess if you do then you do, but I wouldn't expect a lot of follow-up games.
Yes more or less. My point was showing that your last paragraph of that post was well ... pointless.
I think we can all agree that this editions terrain and LoS rules are lacking. It has been mentioned since the beginning of the edition. No point in arguing about it all over agian. What's important is how to help the OP and calling someone who wants to stick to the RAW 'That Guy' definitely doesn't help nor is it particularly fair.
