User blog comment:RayShepp654/How to defeat the Reapers Theories/@comment-1221773-20101031021231

Actually, given the sheer firepower and near-invincible shields of the Reapers, system-hopping is still a pretty good strategy for them. All they have to do is stay together and any head-on attack by Council/galactic forces could be swatted away. In fact, I don't see anything stopping the Reapers from simply charging en masse straight to the Citadel and getting their plan back on track that way. As long as the Reapers keep moving, there's nothing defending forces can do.
