1. Animators who went into boarding because there are few animation jobs available.
2. Boarders who look at OTHER animatics and see that they're partially animated and feel the need to "keep up".
3. Outsourcing to studios means you might get a lot of crap if you aren't precise in your direction, so directors will encourage board artists to spruce up the boards with more drawings so the animators can follow it better.
4. Directors who can't use their imagination will ask boarders to do more drawings that way they can see exactly what will show up on-screen in the animatic phase.
5. The animatics look more "polished" when there's animation throughout, which impresses the higher-ups when the production studio sends it over to be evaluated. This in turn makes the production studio look good and increases their reputation + working relationship with someone like Netflix for future work.
Pic related is considered an animatic in the industry. No storyboard sequence should look like this. No storyboard is supposed to have breakdowns or ease in's and out's. It only started looking like this when boards entered the digital era.
