Yesterday I got Lavellan the rest of the way through Trespasser. A couple of surprises: ( spoilers )
Playing Inquisition as an elf was very interesting, although there weren't quite as many background-specific conversations as there ought to have been. ( More spoilers )
But overall I found there were more specific options, and more interesting options, than for either a dwarf or Qunari inquisitor. To the point that, after I finish my m!Trevelyan based in the Elissa Cousland AU, when I do my brand new full canon run (it's finally time to play the City elf!), I think that Inquisitor will be a f!Lavellan who does what I always said I would never do and romances Solas. It just feels too important to the overarching story to avoid it completely.
