Or Larian can try Obsidian's way used in Pillars of eternity II: a dual system with the option for the player to choose classic turn based, full real time combat or a mixed system in wich you can use "pause" to strategize [the turn system on video games is a bit weird even when in D & D based games, not all that comes from the table top can be transferred on video games, it breaks immersion: first one character (NPC or player controlled) makes a move, then another one, due to the fact that chances of more characters rolling the same initiave, the result is a sort of ballet. Now I'm not a battle specialist but I think that in real battles there's no thing as turns but an incoherent real time battle in wich reflex and perception play the bigger part. The D & D logic videos from Vive la dirt league have funnily and brightly highlighted the weirdness of turn based battles, that again in a tabletop role play game are compulsory, and of long rest not only replenishing stamina, magic, faith, but also healing deadly wounds, bone fractures, burns, cold burns, infections, intoxications, every thing in the same amount of time and with the same amount of supplies, in BG3 is 40.
But those incoherences are part of the charm of the game, just like the fact that you can not heal a character taht is not tied to the story, use resurrection spells or scrolls other than on the party.. ... ]
