I love the Ebonheart Chateau. I don't see the need to change anything about it. I thought that rumbling sound was thunder all this time! I placed a lightning strike at the highest point of the chateau to support that perspective.
I like how a few people can ruin it for others, but usually that's how things go nowadays. Hopefully ZOS will not listen. The oppressive & gloomy atmosphere is what I actually LIKE about the place. Don't change it, ever, please.
I feel that ZOS should truly work more on the atmosphere of houses, most of them you can't even hear the rain while inside etc. (you can in some, even when it doesn't make sense, it's very inconsistent really)
