Yes... and this is related to the explanation they give... I still don't see how it squares with the style of enemies. Aside from things being white... which I suppose is the thematic astral/white color palette, I don't understand the angelic/feathery theme, which to be follows more religious iconography as I stated than it does the overall description of polarity. Sure, some of it looks pretty neat, I am not saying that it doesn't... I just find the aesthetic a confusing choice.
