I've always found Selene to be of most use when playing solo or doing content with people who are less likely to take unnecessary damage (ie people who pay attention, rather than doing other crap whilst gaming). My one gripe has always been Silent Dusk. It's great having a silence that can be cast when needed & for zero cost. However, I'd like to see it have the duration increased to 2.5s (one GCD effectively) & be able to be set to sic (like embrace) even when on Obey. SCH don't have silence from any other ability to my knowledge & it's a real boon in lots of content, especially solo.
