>>149170421 (OP)because the exec cant make an asset library and force you to use it. in digital you can copy pieces and save them for later, and chop up characters and assemble them like a puzzle. to make those assets as universally iseable as possible they have to fit in a narrow rwnge and have wide applicability.
now you COULD redraw everything every time like on paper with digital. and it will still cost less than digital, but they need to squeeze their animation dollars down to every penny.
