Well, now, I'd be more willing to have a reunion scene if the lore allowed for it for the other characters. Miranda and Jack are left at bottom of the barrel throughout the entire game, but still in a position to be at Shepard's side back on Earth. The Normandy simply isn't, not yet.
All the Normandy needs to do is take off. It's really not very hard.
I think my story gains immeasurably. Here comes the famous Xil 'you can't like it because I don't like it' schtick. And I have no sense of petty satisfaction over you. It's an extra scene for people who played with the LI's that weren't focussed on, especially since we really didn't get much of a goodbye on Earth. Citadel was definitely much more touching and personalized for each romance but it still doesn't do everything that it could do.
You may gain by it, but you'd lose nothing if everyone had something to gain by it and not just you/Jackmancers.
You're claiming that you're being gipped out of a reunion. I'm saying that you're not, just that your reunion isn't shown on screen for plausible lore reasons. My reunion is a little bit of content for my Shepard that is personalized to my game. You already got tons of it already by romancing Liara. Seriously, it seems like you're just raining on my idea to rain on my idea.
I wouldn't have a reunion to begin with. I'm not even terribly fond of the idea, because I'm of the opinion that players who commit genocide should probably not be rewarded with cool things. But if we are going for that, your "plausible lore reason" is a paper-thin justification wholly nullified by FTL travel being a thing.
