If Bioware ever decides to choose a canon ending for Mass Effect 3, which one would you prefer?

Except ME 2 has Liara's Father out right state that bringing up the idea of studying the Mass Relays and learning to build their own was laughed at by the rest of the Matriarchs on Thessia.  There is only a 6 month gap between ME 2 and ME3 and during all of ME 3 the galaxy is at war with almost all resources going to the war effort.  Even the Protheans got a proto type working with none to be had or hinted at for this cycle.

I only bring this up because players complain about the hand waving happy ending of synthesis yet this is just as obvious hand waving happy ending for destroy. Other wise the implied repercussions of destroy ending is millions more dying in the after effect of the choice. And that isn't even counting the massive had waving happy ending of only Reapers and Reaper Tech being effected. Which is arguably an even larger hand wave happy ending.

I may be wrong, but I have in my head that the Conduit in ME1 was constructed by the Protheans, not the Reapers. Now, the Conduit is a small-scale science project compared with a full-blown mass relay, but it's a start. It would be the effort of years, if not decades, for the people of the galaxy to a/ reverse-engineer it and b/ continue the research to a level where they could repair a relay, but I think it sufficient evidence to believe that it would be possible.

Where there's a will...

Really? I'm replaying ME3 after a long time, this time with EGM and Back Off installed.

I'm reaching Rannoch with this Shepard in particular, I will come back to share what I've found and to know if I have to bury myself into a hole.

I would also have liked to have been allowed to solve for peace without Tali and/or without Legion (particularly without Legion since my renegade Shep's quite often choose to send him off to Cerberus to be studied).  I don't think I was just being nerdish... the definition of "only" when used as an adverb is pretty, well, definitive:  "and no one or nothing more besides; solely or exclusively" and it seems it literally turned what you posted into the exact opposite of what you apparently wanted to say.  I'm sorry for the confusion.

All I know is that with a high EMS Destroy ending is that the slideshows indicate a shiny happy future for everyone who didn't die during the war. Hence, I have to assume some things, which in certain cases could be either/or. I assume the relays came up in time to get dextro people on Earth back home. Or maybe there are other worlds where dextro food could grow, even if they aren't inhabited by turians (quarians obviously don't have a home other than Rannoch, assuming they survived). If quarians were present, they have the Migrant Fleet. It is already capable of supporting the quarians. They could share with any turians on Earth or even, potentially, lend some of their seeds to plant crops in a greenhouse on Earth (though, tbh, for tourism purposes I imagine such things already exist). Sure, it would take time to grow, but in the meantime the quarians and turians are sharing food. It might just mean they have to ration until the crops grow. If the quarians are dead, yeah, it'll be real tight for the turians but, as I said, there probably already is dextro food on Earth for tourism purposes and presumably it wasn't all destroyed (or else all food would have been destroyed and that obviously didn't happen).

^^^^^ Exactly!

So how do you see synthesis as submission? Is in your mind there only 2 possible out comes of conflict? I mean that is kind of like me saying only small brained idiots would ever pick destroy. I don't like destroy and I have issues with it but doesn't auto mean that only small brained idiots pick destroy.

Synthesis

True. There are people who swear by Synthesis. I did that ending once. Not the worst thing ever. I played Control and felt horribly depressed afterward. Haven't done Refusal yet, but I can't imagine especially liking it. Destroy is the "feel good" ending as far as I'm concerned. I do prefer MEHEM, but even without it I'd [regrettably] sacrifice EDI and the geth.  I do think that any way you look at it, Shepard's story needs to be done.  Does the story of the MW have to be done?  Not necessarily.  I don't mind Andromeda but it would need it needs more, smaller clusters rather than a single one half the size of the MW.

Never mind that trying to justify the Reapers as anything over than "Evil" is frankly laughable if you actually pay attention to what the Reapers themselves Say and Do, that fly in the face of the idea of "Their not evil! really!" Even if they weren't evil, you are correct, that fact is irrelevant. They must be destroyed, to avoid any possibility of The Cycle ever returning. It is the only morally correct choice, for all future generations.  

It is morally correct, because The other alternatives are morally worse by the mere fact the Reapers continue existing, thus leaving a chance, no matter how slim, of The Cycle returning. 

Never mind the fact that to me personally, The Geth mean nothing what-so-ever. I have no sympathy for the Geth and never have. EDI, as much as I like her, is a machine, and is thus less important than organic life to me. 

I could get in depth, and argue that no genocide is committed because all of the losses are machines, but I won't go in that direction because that goes into a totally off topic debate about what defines Life, which is in the end a personal interpretation. And yes, ME3 was horribly rushed, it was a shell of what it should have been, and the ending of it was probably the worst possible way to end the trilogy, from almost ever possible angle. Even more so if they knew going in that this was a series they would work with in the future.
