As I stated, the defenses were mobilizing for the invasion.
How many times do I need to state it? The Vanguard force on Earth alone decimated Arcturus Station and wiped out 3 entire fleets. The bulk of the Turian Fleet, the biggest in the galaxy, was wiped out by a dozen capital ships. It's why the Crucible was being built - we had absolutely no chance in HELL without it. A dozen capital ships were wiping out entire fleets. And there are HUNDREDS of Capital ships.
"Strategically located at the junction of a number of mass relays leading to various parts of the galaxy, the Citadel quickly became a hub of activity."
Even IF they couldn't use the mass relays, the Citadel hasn't moved. Ever. If it did, you're saying the Asari, before they discovered it, just wandered around the Serpent Nebula until they found it?
If you're saying the Reapers suddenly forgot where the FUCK they put their own fucking creation, then you're hopeless. It'd be akin to them setting up a mousetrap and then all of a sudden forgetting where they put it. The whole POINT of the relay system is to flood the races to the Citadel, then the Reapers swoop in, cut them off and methodically exterminate them.
They know that Earth is the stronghold of the Humans and that's why they put the tip of the spear there, but they don't know where the Citadel is.
Right.
And EVEN THEN, that doesn't explain why they STILL didn't shut down the relays when they had control of the Citadel over Earth. They knew the Crucible would be coming, but fuck it, let's leave the relays open anyways and let ALL of these fleets through! It'll be fun!
The Reapers are a retarded enemy in this game. I'm kinda tired of people who either don't remember things that happened in ME1 or are willfully ignoring them.
For the 14th time, because it grants control & charts the mass relay system. It's not about "keeping races in the dark" - it's about absolutely stranding them. Think of it like a conventional ground war - what happens when you cut off supply lines? It completely kills the war effort & turns it into attrition. The Reapers know this game - it's what they were made for. But they just retard around and completely ignore it.
I do enjoy how you're cherry picking certain arguments and leaving others alone, though.
