I will have to say I am a little disappointed that most of the squadmates that I spent so much time in recruiting and gaining their loyalty are pushed to the side for the next game.
Not me. I'm glad to have the old ME1 crew back. The only ones from ME2 I'd really like to see as full companions are Mordin, Legion, Jack, and Grunt. I'm either indifferent towards the rest of the ME2 team, or I just don't like them much.
I'm just happy I'll be able to have my Shepard/Ashley/Garrus squad again.
