dedicated H-bridge-driver

Hi Simon, after studying the afro-esc i asked myself if it's efficient enough to use such a minimal approach on driving the high-side n-fet instead of a dedicated driver for a half-H-bridge. What do you say? The 3 phases can not get near V_in and the high-side n-fet is getting noticeable warm because the fet is not completely on all the time. With just 1$ for 3 drivers the afro30A-ESC could be rated with 60A. Am I wrong?
