A lot of us bought the game thinking we were getting good ol' fashioned D&D
Would you agree, then, that the root of the problem is in Larian's marketing of the game and they should say that BG3 is only "inspired by D&D"?
From the BG3 page on Steam:
Evolved turn-based combat, based on the D&D 5e ruleset. Team-based initiative, advantage & disadvantage, and roll modifiers join combat cameras, expanded environmental interactions, and a new fluidity in combat that rewards strategy and foresight.
I think "based on the D&D 5e ruleset" sounds to me like I should expect them to implement the D&D 5e ruleset. I can imagine myself feeling upset by this; tricked, even, if I was familiar with the 5e ruleset.
