@Lord Rommel,
Like most things, its simply down to taste. I just found the fog effect unappealing and in this case "unplayable" was purely emotive. If fog were applied to, say, Angoville - I'd probably veto that too.
So basically what you are saying, is that you are going to dislike maps to dislike them? And fun fact, angoville has rolling fog on it.
In all seriousness, when you make threads like this, all it does is make the content creators, not want to take anything you say at all for criticism (as you have offered literally none), and makes myself and the others not want to continue to provide FREE content.
Nothing about this thread will be positive, and that is entirely due to the way you have worded and handled yourself.
