Ok you are pointing to one battle where there was something flamable nearby, guess what thats kind of the point of implementing stuff being flamable. If its never gonna come up in a fight it would be pointless to waste coding on it. What I pointed out to you was that DoS combat had a very high frequency of random barrels in the world, especially near places likely to see combat. On top of that there were not only a lot of skills centered around surfaces or having the primary function of creeating a surface but the surfaces were also large and you could defeat enemies with little to no input besides playing around with surfaces.

So you point to one battle that had some sort of oil container to take advantage of, I now point to like 50% of DoS2 battles having one or more barrels to create some type of surface with. I am not making the argument that surface mechanics doesnt exist in BG3, I am pointing out that its way less frequent. So far you have not refuted that and pointing to a single example will not acomplish that either.
