Frame by frame animation is very useful for those who like to draw and who does not want to to spend much time on editing and working with bone. The thing is that they draw their animation using frame by frame. Their cartoon does not require much effort but they need to spend more time on drawing. They can do whatever they want just like they do with bone control. However they will get the same result as what they do using bone control. :D
