I feel very similar despite the fact that I played the game a second time, and had everyone live. When I first played I sat back after getting the device to go through the relay in order to collect more meterials for upgrades. I figured like most games, it wouldn't matter that I waited to go through the relay, that the crew that got taken by the collectors would be dead/saved no matter what. Not only that, but I made some mistakes with the suicide mission, because I had multiple squad mates die, including Mordin and Miranda.
It sucked to lose them and to see my capture crew melted before my eyes, but it made the ending so much more powerful. We beat the collectors, but not without cost. It added weight to my story and honestly I think it was much more satisfying then having all of my squad mates come out unscathed. So when I finally play Mass Effect 3, I am pretty sure that I will be going with my less perfect file, because its imperfections made it unique to me.
