If I can't get a DLC that "fixes" the endings, I would take a simple patch that edits out the destruction of the Mass relays. Because, without that in there, the endings actually sit a little better with me.
Observe (remember, the Mass relays don't blow up in any of these situations):
- You are given a choice to do what you came to do: to destroy the Reapers. But this, in turn, would also destroy EDI and the Geth (who are both your allies, and your friends). It also leaves the threat of a future synthetic war. But it takes the Reapers out for good. There are both pros and cons to this. And, if you forces are strong enough, this is the choice that allows you to live.
- The second options allows you to control the Reapers. This kills you, but the Reapers become nonhostile tools under your direction. EDI and the Geth get to live. Since you control the Reapers, the threat of a synthetic war is lessened merely by Shepard's control over the Reapers (though other synthetics could always be made to threaten organics, the Reapers could step in and stop it). Shepard is no more, but the Reapers remain. Both pros and cons.
- The third option is, of course, synthesis. This completely obliterates the need for any war between (according to the Starchild) synthetics and organics. The differences between them have been rendered void. EDI and the Geth get to live. Shepard dies, but there is hope for peace. However, you are also basically playing god by rewriting the genetic code of every organic. Pros and cons.
In every one of these options, after removing the scene of the Mass relays blowing up, things are a lot more...hopeful. After all, it has already been established (it is story canon) by the Arrival DLC that the destruction of a Mass relay obliterates all life in the system. So you basically just destroyed the Galaxy to save it (but that also means your crew on the Normandy shouldn't be alive either. Plothole). Without the Mass relays blowing up the Galaxy can rebuild. The army you led to Earth can return home. The Normandy crew can be rescued. Life can continue. This also means the Stargazer epilogue needs to be removed.
And the fate of Earth would be dependent on the forces you gathered. If you have enough Earth survives (and you also live if you choose to destroy the Reapers). Though these choices still leave many plotholes and inconsistencies (such as how you squad got to the Normandy, and why it was retreating, and how TIM got onto the Citadel, etc.) it makes a lot more sense
to me.
I would accept this.
