As I improve with my brush technique, I find myself frustrated with my pencils. There's often a texture I know how to create with the brush, letting it do all the work, but doing it with a pencil would take more time than I often have. I think the chances of someone else inking my work are pretty low. The final version will have captions (lots of em!)
Even at the pencils stage, I still make a lot of corrections before going to inks.
For example, I need to redraw the feet on the first panel, dutch the second and fourth panels, and do..something... with that last panel, because it is boring as hell.
