I feel like I should chime in here and say that environmental effects absolutely should be a thing in 5e, and Larian has helped me to see that.
Ever since playing DivOS I started incorporating environmental effects into my 5e and other TTRPG games and they have greatly improved because of it.
Environmental effects are a thing in 5e. There are numerous spells and abilities that create effects within the environment, and those effects have rules for how to overcome them, and then of course there's the theater of the mind aspect in which the DM can rule "yeah your acid splash melts through the lock" or something like that.
The problem is that the environment effects are just frankenstein stitched over from DOS2 and it feels like I'm not even playing 5e anymore. It feels like I'm playing DOS2: The Baldur's Gate Mod.
