Perhaps, but if its only going to make the difference of about 3 or 4 years to get there, and the reaper invasion comes every 50,000 years, that doesn't really seem that significant. Actually, come to think of it, its really for the sake of shock and awe. I actually managed to answer my own question. Since the Citadel always became the heart of galactic civilization, they could wipe out the galactic leaders and then continue on to invade the rest of a very confused galaxy.
