Who's idea was it to ignore player LoS and not NPC?

Sorry but this is straight up the wrongest thing any game developer can allow. Back in FFXI AV "glitch" you would get banned for exploiting the wall but this is being allowed in XIV?

I demand a Hotfix so that players aren't allowed to shoot or cast through the rocks. This is "endgame" we're talking about here, it should be challenging and not an easy exploit.
