Ok so. I JUST finished the game (like 30 minutes ago) and having heard that the ending was garbage I went in with low expectations. I came out thinking it was better than I expected. However, that part I don't like is where no matter what you choose the Mass Relays get destroyed, so I would change that if I had the power. I really don't think the rest of it was bad at all.
I agree... That's what irks me the most. I chose control, but the relays are destroyed anyway?! Really? Yes, I am content with the current ending, and I like the hi sci-fi twist to it, but what's the point of making a choice if it doesn't change the outcome? One would think that only destroying synthetics would destroy the relays, but no. I compared mine with my friend's ending (synthesis) and his was exactly the same! That confuses me!
