I am definitely in the camp of not caring about 5e rules. I dislike D&D mechanics anyway, and if Larian were to take an axe to 5e rules and mechanics I would become their most vocal cheerleader.
However, I also utterly dislike the extent to which the game has those elemental surface interactions. Those don't add "tactical depth." They're just annoying, tedious, silly cheese. It is ridiculous that there would be all those surfaces so very conveniently available exactly where you want them exactly when you want them. Furthermore, it is also ridiculous that so many barrels of oil are just lying around everywhere waiting for the party to gather them up and cheese with them.
