I like to do DPS on scholar but I find that even without Whispering Dawn etc I don't need to pump out too much extra healing manually, again, largely because of the difficulty level of the content I do. I'd certainly never advocate not using Eos if you need the healing, and definitely not leaving her on Obey.

I guess what I'm trying to say is I don't think Selene is quite as useless as people make her out to be. Silent Dusk definitely needs to be replaced with something useful but there's a certain level of histrionics I see (not so much on the forums, but in conversations I have in game) that make it seem like if you have Selene out you're not gonna clear content. Which is not true lol. It just works out well for me that Selene isn't that garbage and unless I need to save the cleanse for some specific thing, I can more or less just leave her on Obey and focus on what I myself am doing.
