I think in this particular case the conversation system was OK. Because the commander doesn't have much time to chat with his/her new friends, there's darkspawn threat, people are dying all around the arling, and we must act quickly, not try to bed Anders XD Though if Awakening could be longer, I would prefer to talk to my team directly.
And I love the party banter. Velanna and Justice are one of my favourite, because she eventually agrees with him and gives humans the second chance. And I love the conversation between Anders and Velanna when he tells her about Rylock. Hell, I love all conversations with Vel, she's adorably wild.
