Forgot to add, the point that Solasta allows readied actions and BG3, to my knowledge, does not, is an important part of this discussion. In Solasta, I believe you can have your readied actions trigger, based on a preset condition being met, as part of your reactions. In these instances, the reactions happen automatically, resulting in surprisingly smooth-flowing combat. So the inclusion of readied actions seems to be a crucial element to making all of this come together well.
