Could someone please summarise the main points people are so pissed off about with regards to the ending? I get that the post credits thing was dumb and choices from the first 2 games didn't make much difference but other than that I don't really see what was so offensively bad. Certainly it wasn't as good as it could have and there's stuff I'd have liked to see that wasn't in there, but thats they only have so much time and resources to make what is already a massive game. I don't see why people are treating it like its worst ending of all time and that people actually think bioware should change it seems absurd.
you screwed every single thing up, because of you, 1000's of people are going die. everything you did, what you fought for was for nothing in the end.
and no matter what ending you get, everyone is screwed, all those fleets around earth can't go home. there won't be enough food to survive. earth is burning. all your friends, ended up somewhere random or are dead.
all the work you spend getting everyone to trust each other no longer matters, since no one will ever be able to see each other ever again.
and there is probably more
