The chain system is simply broken. As RedQueen says I'd rather have these QoL suggestions implemented instead of none of the but the language of "reasonable ask" is nonesense. No one actually likes the chain system. They can tolerate it, the fight can be made easier to or harder but I just don't like feeling like I'm fighting the engine when I'm playing.
I assume it has more to two with BG3 being a bit over 3 months away, than being worried of upsetting Larian.
I share your and Tuco's view on the chain system, but changing how character's move would be a major change - I don't think it would qualify as QoL improvement, and that's what the video was about.
