Cole (bringing him sets up his personal quest perfectly) and Solas (Fade expert) are a given, the last spot is debatable. Unfortunately, the presence of two spotlight-hogging uncontrollable NPCs (Hawke/Warden) means that the people I bring because I actually care about them and want to hear them talk get sidelined most of the time, so #3 doesn't actually contribute much of interest even in situations where they logically should.
Cassandra is okay as the "filler".
Bringing Cassandra along and not Varric is interesting, and makes me wonder what happens if you don't have either of them along.
