Fiery Keeper of the Hat
Sorry, it's not true. At least for marvel and DC (perhaps not so much for indies), there is a very extensive creative team that starts with an editor, who is responsible for assembling said team. Which does in include more than one writer and one artist.
I'm not sure I understand the point you're trying to make in regards to the conversation about writer and artist workloads. But while Marvel and DC do have editors and a creative team, and often do crossovers with their writing teams, and their writers probably have assistants, and their artists probably lean on colorists, and so on..... most publications still come down to one artist and one writer.
Managing through the creative hierarchy only serves to increase the workload on the writer, who has to justify the story upwards and far in advance... and working with a colorist reduces the workload on the artist, which does a lot to bring the workload on the team closer together.
It's another thing that separates Marvel and DC from new or independent comics writers, looking for an artist.
That's not writing, that stage direction. Actual writing tells an artist to draw Spider-man opening a can of soda because it is important somehow to the story.
But it wasn't an example of writing. It was an example of artwork. Spiderman opening a can of soda is relatively easy for an artist to do. A new character opening a can of soda is a much larger creative undertaking for the artist. That shifts the decision-making workload from writer towards artist for new/independent strips compared to established characters.
All of this comes back to the main question of the thread: Is it realistic for a writer who wants to break into comics to be looking for an artist? OR, is the project too much work on an artist for a writer to expect it to work out?
