I will repeat once more, proper reactions and ready actions do a lot more to open up a new dimension of tactical thinking than anything else that can be done. It means playing defensively is a viable option, some reactions let you directly defend yourself in some way against an incoming attack, and they let you try to anticipate what an enemy will do during their next turn so that you can outright punish them as they act. All concepts that I struggle to see anywhere in BG3.
They encourage proactive strategies rather than the heavily reactive (ironically) emphasis that is present in BG3's current combat design. Whatever proactivity there currently is tends to be largely restricted to setting things up for major surprise rounds and/or starting on super high ground somewhere.
One can argue that Solasta's implementation isn't perfect depending on their opinions about its presentation. But most people universally agree that the complete lack of any coherent reaction/ready action system in BG3 isn't really an answer.
