I love kde for the functionality and the development skills. But I like the GTK adwaita style a lot more and gnomes design improves every couple of months although all the apps are in a different state right now which isn't the case for kde. Kde apps all look consistent but that's just because nothing has changed in the past years I guess. Moreover writing apps with GTK seems to have a lower barrier to entry with python et al compated to C/C++
I think KDE looks nice but what you said makes it seem like it's questionable to make a gnome theme over a KDE one? I get that you don't like it but the person who made this probably uses gnome like you and wants consistency, or just likes the gnome design. So if that's the case why would they make a KDE theme?
That is stupid me, I thought it is something like a request. Even now I looked closely I think I tried some other theme and I will test this one too, maybe it is better, than that I tried before.
