But for gameplay, being stuck with a broken build is a game killer for me. I don't want to start a new game just to fix a build mistake.
Absolutely agree with you here, realizing 30 hours into a game that you've built your entire character wrong feels horrible and some respec should definitely be possible. There has to be a sensible limit though, as some things are so integral to your character that they shouldn't be touched. That degree, I suppose, is a matter of preference. Personally I think ability scores, feats, spells and subclasses are fair game, but race and class should be off the table.
I believe Pillars of Eternity and Pathfinder Kingmaker/WoTR handle it well. PoE lets you respec your build for money proportional to your current level, allowing you to redo all of your attributes and talent choices but not your class or race. The Pathfinder games offer a complete change of your character including race and class, but there is both a cost and a narrative explanation (professional magic-aided retraining iirc) and the amount of race/class reactivity in those games isn't even remotely close to what we're getting in BG3 anyway. I think Larian should seriously tone it down if the OP is accurate.
