My read on what he and others were concerned about was that DA Origins introduced an aesthetic of low fantasy, dark and medieval themes. Many felt, including him, that the new characters felt like very generic MOBA-style designs that didn't feel particularly at home in the DA world they hoped to see. Since some channels have gotten to play the game now the outlook seems to be changing with some creators saying the trailers and released material did a poor job of showing the overall art direction. Also, it seems fun, that helps. Keep in mind, a healthy concern over Bioware is very warranted these days.
