I thought Larian's whole approach was to allow players to play (and enjoy) the game however they want. I strongly favor melee combat over everything else including especially spellcasting. Why is that "playing badly"?
Generally the idea of tactical combat (and especially turn-based one) is to encourage well... tactical decision making. Though if that's not self explanatory then I understand why TB come from - bad combat is easier to ignore if it plays by itself. Bum rushing an enemy on a higher ground, with advantage, with all party members, with one units far ahead of others, hoping for RNG to smile you you... I think it would be an insult to not be punished for that.
With what seems like a wide range of utility items (like smoke arrows and such) I hope BG3 would allow for range of interesting strategies even with physical combat oriented party.
