I fully support a re-do to save Tali on account of how incredibly misleading the prompt is when selecting the other fire team leader. Miranda says "command loyalty through experience." That completely deflects the decision from straight-up leadership - Samara objectively has the most experience of the crew, with Zaeed and probably Legion next in line, yet none of those are correct choices. If they'd written it as "with leadership experience" or "an experienced leader," it would make perfect sense (and be much more normal ways of phrasing it), but if you're putting more weight on the dialogue than the selection menu, it hoses you.
I think it's entirely the writing's fault. It's telling that Alex not only chose the right people in each other case but that his short list for each also included the other correct options.
