Since I changed over to post production processing with mods and thus got realistic pitch blackness working for Dr. D'Irsei and Jordis to travel through, Aura Whisper has shot right up the list of most used and appreciated shouts. It's probably third behind Unrelenting Force and Ethereal.
Ice Form was a staple almost all the way through as well, and still gets used when a particularly nasty enemy within a group needs to be completely neutralized rather than simply thrown like a rag doll. The Dr. has also taken to using Storm Call more, though Jordis is not happy with her for that. In case you think stuff like Storm Call is overkill given ones power at later levels, I am running the Wars In Skyrim mod which frequently has the two women walking into skirmishes between 15-20 people at once, and sometimes animal attacks in multiples as well.
Shouts that reach out and touch many at once are a boon again.
