Even if characters dont always set on fire, if the floor is on fire that constant ticking damage that is way more than a cantrip should ever rightfully do.
Then theres the -2AC acid surface that is just... insanely overpowered for a cantrip.
Surface effects are a DOS thing not a DnD thing. It's telling that playing this DnD game is easier when using DOS playstyle and slamming your head on a wall when doing it in a way you'd play DnD.
