I have seen examples from Larian's data analysis like that the Bless spell is not used by players because they find it "boring".
Did they really say that?! True, I used Bless once in my BG3 EA playthrough. I use Bless regularly in Solasta. #BalanceMatters
I don't know if I can find the quote but I do remember them saying that almost no one in their data was using Bless and they figured that was because buffing was boring and not thinking, we borked play balance so bad, Bless, one of the best 1st level spells, is not needed / being used.
