I really am glad he was added. I do think he should have been an original part of the game, and not a DLC character. I've never really paid much attention to him before, but I've been using him alot this playthrough.
I'm really impressed.. Not only is he a bad ass on the field,... the guy just got his arm blown off and carries Kaiden into the Normandy!!! I have never taken him with me on my final mission, so it is something new for me. This game never ceases to surprise me.
