I've mentioned it in other threads but I still feel like the way to make Baldur's Gate the most accessable to both people who like the Divinity series and people who want a faithful recreation of 5e is simply implementing difficulty the same way as BG1 and 2 did. If you wanted the full 2e experience it was there for you and all the missed dice rolls, memeber deaths, and action ecomony etc. were there for that experience. I think that's where BG3 should start and create that authentic 5e experience to start with in EA and then move onto changes for other difficulty settings that provided more quality of life changes to either player health, monster stats, extra spell slots, not needing short rests etc. A faithful 5e recreation is going to be a brutal game though, the unfeeling and uncaring DM that is BG3 has no issue with wiping your party as soon as possible and it's not hard to see why people just aren't a fan of that.
