I didn't see any of the stuff the OP was commenting about.
He never said they didn't make mistakes, he simply defended the choices the design team made. He even admits that a lot of things still need a lot of tuning. He simply states that the team is happy with the direction they're going, and are going to incorporate fan feedback without doing another 180. He even explicitly says at the end of the interview that player feedback is very important to them.
He says a number of things need improvement to continue the game's growth, especially in the combat area. Saying he's happy with where the game is going =/= not thinking anything needs to be changed or tuned.
The OP's definition of depth is different than other people's. What makes this so difficult is that the fan base tends to be fairly evenly divided (from actually talking with people, and not just reading the slams on forums). For every person that loves that companions have a unique, signature look rather than all looking the same, there's someone that really loved the control over companions' armor. And the OP seems to be completely ignoring the fact that Laidlaw said they are exploring ways to get the best of both worlds, where companions get a signature look and the player has some control over what they wear.
As for the tactical camera, it was a mechanics issue, and again, I didn't see him disregarding people's outcry to the changes, just standing by the direction the game is taking. I can see their point. I loved the more vast areas, and catering to (a) only PC/Mac players, and (b) only those that extensively used the tactical camera is not the way to go when you're dealing with a wide player base on multiple platforms, not all of whom use the tactical camera.
Game designers can't please everyone. There comes a point they have to say "This is where we're taking the game." This is not disregarding fans that dislike the changes, it's simply impossible to make everyone happy. What I gathered from the interview was "We're happy with where we're going, but we're taking everything into account. While we won't do another 180 and revert back to Origins, we're taking criticisms under advisement and looking for ways to create a middle ground that will bring the two sides together."
I really feel that people that react to this as "Just more proof the DA team sucks" are those that feel that their concerns override others who enjoyed the changes.
