You're right though. ME3 DEFINITELY delivers in the humor department. I like how Bioware included some references from internet fandom as well. You know they're reading the forums.
And actually, I kind of like the less dickish Renegade, at least when it's toward the crewmates. I used to hate having a crewmate spill their feelings out to me and then I answer with a "Who cares?" or "F*ck off." type of response.
