Reading about how hard it is to get approved for a manga, even back then always gets me. Getting rejected for years sometimes and then having to make another story because it fits the criteria better is not too great.
I guess it is a job afterall and there needs to be some edits to make it more appealing, but i feel like a lot of nice storys get denied, due to that as well and thats how we end up with all new manga/anime feeling copy pasted with minor changes, as if made by committee.
