The story telling in general has been a big improvement I think. But the vex suffer because we don't have, and have never had, any meaning communication with them. Plot points are always more engaging when the characters are more involved. I loved calus... he was a great character and enjoyed all story arcs with him (osiris and nimbus perhaps detract during lightfall but they're still engaging). The witness/cayde made the final shape! This season we get two mopey boys, and no big bad (yet????)... so the only conversation we get I kinda want to ignore. Although, I like failsafe but she's working with duds (characters, not actors)!
