Yeah, they were absolutely right. Strategically, it was stupid anyways, and in retrospect it would have accomplished nothing except leaving the Citadel less defended.
Pretty much almost everything the Council does is 100% reasonable. Of course they didn't believe Shepard, his evidence was a dream. Then when he semi proves Saren's a traitor, they DO take action - they send Shep after him. Then when he proves Saren is building a colossal army, they take action by reinforcing all roads that lead to the Citadel. Totally. 100%. Reasonable. And their inaction in ME2 is perfectly reasonable too. And their unwillingness to throw their fleet at Earth at the Alliances request in ME3, voting instead to play the defensive against a hopelessly superior force is absolutely reasonable and strategically sound too.
But Shep and everyone are like "man the Council is such a bag of dicks what's up with that".
True. I don't disagree with most of it.
But, like some have said, it's revealed in the Citadel DLC that they always knew the Reapers were real, so why didn't they support their best chance at defeating them, a.k.a. Shepard? Or at least come clean with him/her?
Hell, this person defeated their best spectre, a powerful matriarch, stopped a krogan clone army from being made, and killed a sovereign-class Reaper.
If they were worried about the population finding out, they could simply have worked in the shadows with Shepard, giving him/her resources, intel, but they never did it after ME1.
They could have directed Shepard's actions or at least exerted some control over him/her if they planned together for their arrival.
Besides, in ME3 the most obvious strategy is to unite every single race against them, not to take back Earth right away of course, like I've said before, but work together since the start and direct all the fleets to delay the Reapers, buying Shepard time to find out what the Catalyst is and recruit everyone.
The asari councilor says "I apologize for being so frank Commander, but your plan seems doomed to failure, we know, we've been there before."
"We must focus our attention on the arrival of the Reapers" "So no, the asari will not be at your summit"
What the f*k do you mean by focusing your attention on the arrival of the doom army of hell? How does that alone help the survival of the galaxy? Don't you think you need to prepare for that? Like, with everyone you can?
They withheld the most important source of information in the war (the Vendetta VI) because they didn't want to upset the balance of power in the galaxy, they said.
So they thought the reapers would never come for them later, and would just stop attacking the other races? Or they thought the others would be able to defeat them alone? Clearly, they didn't have a f*****ng idea what was happening on the rest of the galaxy or it's just plain bad writing for the sake of emotional and dramatic moments. Guess what I think.
If they revealed the Temple of Athame on the first visit to the Citadel, Shepard would've recovered Vendetta, learned what the Catalyst was when the Crucible was complete, Cerberus would've never gotten their hands on it, and the war would've finished a lot sooner, with no need for that huge battle over Earth and not as many casualties.
And, despite all the shitstorm the asari would've faced for withholding prothean technology, they would still have relative dominance over the other species at the end of it.
On a side note, I think the Dragon Age franchise is much better written.
