My #1 critique of BG3 from Day 1 has been that it is combat and not roleplaying that is central to the game. And in such a game, it is very natural that players will gravitate towards min-maxing, which I fully expect 90% of people playing BG3 to do, because it is the DnD thing to do.
This was indeed my major concern regarding BG3, after playing both DOS and DOS:2. Both games were combat focused and unfortunately the world and story didn't click on me the way I hoped (it wasn't bad, but it wasn't great either). Now, I can't tell anything about BG3 in this regard, because I avoided to play EA, to not spoil the full experience, but there is an interesting interview with Swen on Polish site,
gry-online.pl, where he said there is relatively low amount of combat, and you can deal with most situations using persuasion. Now, I obviously can't judge if it's true or not, but that gives me hope, there will be a lot of space for roleplayers, like you and me.
Here's English translation of this part of the interview:
GOL: There is one thing about peaceful solutions in the approach to quests that I had in mind. I felt that in those days Baldur's Gate was more focused on combat, comparing it to Planescape: Torment or Fallout. Do you maintain this approach to clashes in BG3, or do you give people complete freedom in how they can resolve potential conflicts?
Swen: You have absolute freedom. There are very few fights. You can even ally with Gorthas. And it's literally to ally, he keeps his word. So you don't have to fight with him. There are many persuasion options in this game. But there are some fights that need to be fought.
