They make it all look sooooo easy.
It doesn't take much time to read a comics page, but it's incredibly time consuming to draw a comic book page.

Comic pages are typically drawn in pencil first, then finished with a variety of techniques. The time it takes to fully realize a page in a color comic is so labor intensive that most comic companies divide that labor between a handful of specialized artists.
The inker – who is sometimes the sole illustrator of a comic – finishes the penciled art with ink, or a simulation of ink in a computer program.
Not all comics are produced in an assembly-line manner, but when they are, the penciler usually gets most of the glory because they're the ones laying out the story based on the writer's plot, and define the general style of the art. But the inker's job is to make the art look as refined and professional as possible.
