No!!! Cereberus could NOT have built that big of an armada. EVERYWHERE it's stated the time and effort it takes to build a ship. Hell even the SA only managed to build 2 new dreadnoughts during the time after ramping UP the building speed, since they had a bigger part in peacekeeping after ME1. But Cerberus, which over and over is stated as a small organization all of a sudden can conjure up fleets that threaten the alliance out of nothing?

WITHOUT ANYONE NOTICING A DAMNED THING!!

Just another of ME universe's MANY plot holes.

The biggest "plot hole" actually is that this overlord AI with reapers in dark space ONLY cares about OUR galaxy. They're already in dark space, shouldn't they have sent feelers out to other galaxies during their over 50 million years of existence, or is only OUR galaxy teeming with life but the rest of the universe as dead as the Soldier of Fortune franchise?

Citing Bioware's lazy arsed attempts on making up in game reasons for the plot holes are not an answer. Remember all those answers are bad retconning attempts. The answer is: Lazyness! /Thread
