Exactly that one little change and all would have made much more sense. Of course we still could have tried to jump in front of her and we still have the problem that seemingly on one side we should be afraid of Mikoto dieing (someone who still can fight) from one bullet while lots of character survive far worse. But just that one change would have made it better.
So true. They even said that doing something while we are in there could hurt us (still could have at least gone to the traitor to hit her as soon as we are back...they did not know that there would be a primal after all), so they are all standing there while we could have now been easily killed by a sniper or something...imagine if the shot at the end was from an enemy and not a friend...so taking the risk of letting your most valuable ally go into this is just stupid.
No sadly echo powers, especially powerful ones like Mikotos, are only allowed to exist when the plot needs it. Either dont give your character such usefull tools (we also never seemingly want to train it so that we are not forced by its hand and can use it when we want to...) or plan the plot according to that power. Dont just ignore it when it would be great to have.
