Yupp. And despite what Larian my see in a lot of memes around DnD critical fumbles and fails on those checks are simply one thing: terrible. I will never understand people who enjoy them, especially critical fumbles on attack rolls. Those people are making their game effectively worse.
I haven't played with critical fumbles in ages, but it really depends on what system for it you are using (automatically stabbing yourself in the foot is always going to be the least fun way to do it) and what kind of game you are running. I'd be a lot less interested in having them in a long, more serious campaign.
But there's also a big difference between critical fails and critical fumbles. Critical fail is just 1 = failure regardless of modifiers and I think there is some legitimacy to having them for certain kind of skill checks where failure is always an option.
But that aside, I'd rather BG3 didn't do them at all.
