Well that's fantastic.
I understand your point about the artwork not matching the character. That, to me, isn't even the crux of the post.
The "errors in character sheet" don't lie in the fact that the sheet doesn't match the comic, but rather that the sheet and the builder doesn't match.
Also, Zaran, perhaps part of the reason why he was made a "Knight" is that there is the closest thing you can get into a Warlord with the Essentials stuff. Of course, I don't pay much attention to 4eE, but there perhaps is an Essentials version of a Warlord out there..
