A really good combat-oriented DM will keep your party on the edge of death most of the time. It's what makes things exciting.
What BG3 really needs is a better set of tooltips to ease players new to 5e or players coming off of DOS2 into the system. Really emphasize Advantage vs Disadvantage, how the action economy works, guiding them into abusing the environment and the effective ways to combo with the party. Basically, use everything, unchain your party frequently, scout effectively, know how reactions work (how to intentionally trigger them, how to deflect them, how to prevent them), and use the right Action vs Bonus Action at the right time.
My observations from the forums and steam is that players familiar with tabletop are doing quite well, players from DOS2 have the right ideas but aren't familiar with the spells and systems enough to put them to use effectively, but players from BG1 & BG2 are really struggling because they're still used to the 2nd Edition rules and balance.
