I'm not playing the EA myself, but from what I got out of the Update and Swen's presentation the main thing they toned down was the companions constantly having a (mostly negative) reaction to EVERYTHING the PC says/does, including even when they're not physically there when the PC said/did something. Seems eminently reasonable. Someone can be as dour or sullen as they want to be and yet make a choice that they're not going to respond to every single thing the leader of their group says/does that they dislike. This is what is actually normal behavior.
If it is merely this I'm fully on board
