I played acts 1 - 5 on insane difficulty as Dom and by the end of act 5 the I cant quit you dom achievement didn't unlock. I did not play through the training part at the beginning of act 1 so I re-played it as Dom and used an idle controller as Marcus. I made it to the end of the chapter but the achievemnt still didn't unlock. Will not going through the training void the entire section of act 1? Please help me it's not fair that I justly fulfilled the requirements of an achievemnt and did not recieve points for it.
