Yes, because the problem with comics is high-quality, glossy, paper with dynamic artwork and a realistic range of colors. Go back to the pressed-pulp recycled paper and 4-color, rough artwork!
It's a problem, not the problem.
And as much as I detest Manga, the black and white format printed on cheap paper has worked quite well for them. Being more affordable means more people will buy it.
The other problem as mentioned is the focus on superheroes comics, mostly thanks to Marvel and DC.
