Breakfast Topic: Arthas is tall, y'all

So while running Trial of the Crusader and ICC, I keep noticing how tall Arthas and other supposedly human-sized bosses are. It's one thing for Marrowgar to be enormous, but standing in front of Arthas and having him be easily twelve feet tall has always kind of bugged me. It's bugged me ever since I first ran Tempest Keep and noticed Kael'thas was similarly embiggened by his raid boss status.

Don't get me wrong, I understand they're not literally supposed to be giants - like when I talk to Jaina in Hyjal Summit, I understand she's that big for our convenience so we can find her and click on her more easily. It's just always been a bit of a disconnect for me mentally. So let's look at it this way - are there any disconnects in terms of raiding that break your suspension of disbelief - like supersized bosses, or how Nazgrim has an entire room full of adds but if you pull them outside of the room he just gives up and goes away, or how raid bosses who are fully aware of our presence like Nefarian in BWD will just sort of sit around and wait for you to get to them instead of coming to you while you're fighting one of their minions? Let me know.
