Just throwing my 2 cents regarding the discussion in the few previous posts.

I'd like for ancients to have a better CD.

And about devotion, I am thinking that it didn't get all the attention it needed mechanically. While I wouldn't necessarily call hypnotic pattern a thematically appropriate spell for the oath of devotion, I am thinking it needed sth very much like it. I dont know, compared to the not-so-nice oaths, devotion seems to be lacking some synergy between its features.
