So far in BG3 Arcana, Religion, History and Investigation has come up I think.
The fact that it has come up doesent make it worth taking over other things. More often that not you succesfully gain information through other means, which involve talking and spellcasting, and other stats have more to offer, wisdom is used to resist things as hold person and shake off mind affecting spells etc.
The only use in normal dnd games were RP reasons, to play as 'smart' character, here it doesent matter at all, you dont get affected if, say, your int was 2, you would barley notice it (unless youre a wizard).
Well that's your opinion. I personally see the need for Int when I can get it. The fact that it comes up is why you want it. Sure you can do it other ways, but so can most other stats too.
But yeah 5e is one of those games where not all abilities are created equally. Wisdom is OP because of perception, and how the game handles it. Charisma is OP because you are the face of the party and how the game handles social encounters.
Strength is OP because of jumping and carry weight, and how the game handles inventory. Dex is OP because of Larians inability to understand how armor works in DnD 5e. Constitution has always been a "do not dump" stat.
If Larian just does things a little differently, then the other stats suddenly becomes just as useful as at the table top, where dumping stats is a thing. (Except for constitution)
