Yes, f*ck those timing charts!
When animating in TvPaint, You often gonna use the Lighttable function. I love it.. Much better then a real light table! Look at the psychedelic colours. And the pattern it makes. Animation fascinates me, at least 2D - You really have to think organic, in arcs, and feel out every pose you draw. (Um thought some of them can be extreme!)
I plan in drawing, in arc, and the movement ahead in 2D this way... Many animators do THUMBNAILS before and, then key poses, after that TIMING CHARTS. I make thumbs, then I plan in drawings.
