User blog comment:James12708/What we know about the Reapers and what I thought would happen in Mass Effect 3/@comment-24174486-20120814200132


 * 1: Even without their shields, Reapers are still significantly strong. Turning off their shields would help, but it wouldn't guarantee victory by any means.


 * 2: The Reapers wouldn't need a majority of their forces to defend the Citadel.


 * 3: That's almost exactly what happens in the game. They seek the means to controlling the Reapers, and the Crucible may allow you take over the Reapers yourself.  I also seriously doubt that a Shepard of the sort that you describe as a "Renegade" would favour the krogan automatically, especially if Wreav is leading them.
