A batarian squadmember would have been interesting and a clear representation of the unity that Shepard is bringing to the galaxy.

I would have liked more conflict and mistrust between squadmembers like in ME2, since they are incredably different in their natures.

The Collectors are not all dead. The Codex entry "Miracle of Palavan" states that Collectors were amoung the ground forces on Palaven. They may have been wiped out by that point but who knows.
