Jacob died for me, sent him in since he volunteered even though my heart told me to send tali. I romanced miranda my first playthrough but like tali way more, just felt obligated to do miranda tbh. Honestly I think it was pretty obvious you're supposed to choose samara/jack/morinth for the biotic barrier because their biotics are way better than mirandas story-wise. Oh yeah zaeed died too. But who the fuck cares about zaeed.
