I don't care that some of the UI stuff looks like it carries over from D:OS2, even during the EA. I'm sure it will get changed before the full release, and it's certainely not worth getting pissed over. I give the benefit of the doubt to Larian yet.
Funny, I remember following the developpement of POE from the beginning right until release and some of the last footage they showed, like a month from the full release, they were still using the spell icons and some UI items from Icewindale, like litterally. No one complained, yet it was copying another game...
