Even after the reaper is destroyed, Anderson is still able to contact Hackett who is escorting the Crucible. Anderson also mentions that Hackett told him several Sovereign class ships, including Harbinger, are headed there way.
The only interference was that they couldn't fire on the destroyer until it was away from the beam.
Major Coats: Can we call in the air support to deal with it (The Destroyer)?
Anderson: Negative,some kind of interference.
Because it would be quite inefficient. Relaying orders through an intermediary will only hinder military operation. It will also be impossible to simultaneously contact multiple ships, and an operation of that scale would require constant communication of that sort
EDI could've easily contacted Hackett and tell him Shepard needs Harbringer distracted,and,based on your EMS Hackett could've either sent a few ships or not.
Its a simple fix and makes sense story-wise.
Bioware had a small plothole - the squadmates you took with you in the beam run and how they ended up on the Normandy which i could live with - and because of whining about that decided to fill it with an even bigger plot hole by having the Normandy do a FTL manuever with such precision right in front of Harbinger. And Harby didn't fire. Now we have something the size of a canyon. Don't think about it. Don't think about it. Just enjoy the goodbye moment.
This was one thing the Original Ending got right. The squadmates getting up to the Normandy was very minor from a cinematic standpoint. They should have left it alone.
What needed to be changed was the last five minutes where the immersion was completely broken. The EC did not fix that.
Totally agree on this one. The only possible explanation is the Reaper IFF,but still,if the Normandy participated in the battle above Earth its impossible that Reaper's wouldn't have figured it out. After all Harbringer knew the Normandy had the Reaper IFF since its the only way they could've survived the Suicide Mission.
