Re: Question about ending
@kms272; Cassandra is a full "Companion". She can join the Party and travel/fight with the Inquisitor. Leliana and Josephine are "Advisors" and, except for brief scenes during their respective PQs, they never leave the base (Haven/Skyhold).
The Inquisitor can select Leliana or Cassandra (or another we haven't even discussed) for a particular "post-game" role. The implications of that choice are... unclear (DA4?) I guess this is what people are talking about when they like/dislike the ending. But it was their choice, so what's their issue? Whichever is selected behaves exactly as all her previous behaviour would lead one to expect.
That said, Josie is a potential Love_Interest and can be romanced by the Inquisitor. Leli, on the other hand, remains the Ice Maiden. (I guess she still carries a torch for the Warden... 🤔 )
[EDIT: Oh yeah, for the sticklers out there: there is one other time Leliana fights. But that is in an "alternate" location. And she still isn't a "Companion". 😉 ]
