@Terminator-HIX A frigate can destroy a full-size Reaper, but that's not a single reaper, they are few thousands of them, that's why a miracle or overpowered superweapon was needed. If we ignore the Catalyst and Shepard could somehow destroy Harbinger as the oldest and the largest Reaper and leader of it's kind, they would not be so organised like ants with dead queen. It could postpond them and Shepard would buy some time to activate the Crucible.
