Have you played the latest patch, Clawfoot? I only tested it a little bit myself, I'm currently waiting for new classes and whatnot to be added before I make another deep playthrough, but what I want to say is, when I tested the freshest version the environmental/surface damage seemed to have been diminished a bunch.
Yeah, I noticed this too. I think they only deal damage when you walk into them/start your turn there/end your turn there now, which has severely decreased the amount of damage they do.
