Filmation did re-use a lot of animation. Once a show got popular enough, they would re-use assets from other episodes and just time save a lot while keeping costs low.
I think they had to. They had a stable of six shows running at once at one point. Some corner cutting was necessary, even if I didn't like it as a kid. :)
And that's if they're always constantly moving. It's less if they're just standing around talking.
Filmation was notorious for this in the '70s and '80s, cutting corners whenever possible by having lots of dialogue, but little to no movement.
