Heck, even cantrips have surface effects automatically, which almost makes them better than level 1 spells.
Not sure I agree there. Firebolt has had it's damage reduced by quite a lot from it's 5e version. Ray of Frost is supposed to slow down enemies, and that's exactly what it does with the frozen ground.
Honestly I think both of those cantrips have become worse, not better, in BG3. Why? Well ray of frost now requires a save to see if you fall or not, so it's not a consistent enemy slower. Firebolt is no longer a consistent damage dealer.
I don't mind though, I like that they have some utility, I just don't see them as overpowered in any regard.
