Madara and Hashirama cancelled each other out by engaging in the battle, so it was better to remain that way. Plus, just to remind, if Minato sacrificed himself to bring out Madara, there would be nobody to use FTG in order to save the Alliance from Obito's four TBB within the barrier.

Ok but then why couldn't Minato use Reaper Death Seal on Obito? Hiruzen wasn't much help at all when dealing with obito and it didn't seem like you had to stay in one place in order to hold the barrier since Minato teleported to obito and left his place before Obito became the TTJ. So Hiruzen could have been much better dealing with Madara. Even if Hiruzen could make Madara's hands disabled as he did to orochimaru, it would have been great help than just throwing shurikens which don't do much in the naruto universe.
