It's dumb because it dissproves IT?
It makes sense within the setting. The more time you take on getting War Assets; the more time we have for the Crucible. If you rush the whole game, without completing any side-quests, that means we had barely enough time to make the Crucible and that your defenses suck.
The reason why it's possible to only have Control is probably because you had the Reaper Brain, which most likely helped the science better understand a part of the Crucible (the Control side). If you had the Reaper Heart, then they better understood another side of the Crucible (Destroy).
That mechanism should have been explained better.
If the Intelligence truly didn't want Shepard to choose Destroy, it wouldn't even mention it. Yet it does. It says it's not a good solution but it still offers it. It also offers Control but says that it doesn't want Shepard to chose it.
Shepard went there to Destroy the Reapers. That's been his objective all along. He wasn't even allowed to entertain other ideas when theyvwere suggested. Nkt offering a Destroy option makes the hallucination less credible. Alternatively, Shepard is particularly strong-willed and is able to insert Destroy into the hallucination himself (this is actually backed up by Leviathan, which identifies Shepard as singularly threatening to the Reapers).
About the epilogue slides, I'm gonna give you an example. In Synthesis, Shepard dies. Why would the Intelligence show him a world in which he is dead? He's dead, he's not part of this world anymore, he can't see it. The answer to this is: because it's not being show to Shepard. It's being shown to the players.
I wish the game wouldn't do that.
So the world stops moving because Shepard is dead? Really? What kind of logic is this?
Shepard stops witnessing it. Shepard is our point-of-view character. If Shepard doesn't witness something, neither should we.
And Shepard is there to witness them in the Control ending, he's the new Reaper master consciousness. He's also there to witness them if he survives in Destroy.
Control I'll give you.
Does FTL communication still work after the mass relays are destroyed/damaged?
