The story need testing too, how could you deny that? LOL. It's BG3, not a random IP, 1 and half a year of EA without any further narrative? How can people evalute it? It would be questionable.
If you don't want to get spoiled you can stop at act 1, btw. Just keep testing classes/archetypes and mechanics.

Also, I repeat this: there are literally 0 statements of Larian about it, how can these guys up here be so sure?

Tbf I'd like a roadmap and some clarity on this topic in the near future. So we can live on in peace, without people like this Tuco guy right here laugh (Bro, you can stop commenting btw, I got your point. You r an hackerman with deep intel, gj)
