Endgame Game Mode Critique

They need to make it so when there's one last hero on the map and the enemy team can't respawn, that the hero can't just fly infinitely around the map when there's only 5 villains left. i had my match held hostage for hours because the last hero just kept flying away from us with Iron Man's Jets, and we couldn't do anything because he was too fast. this is terrible game design, and I'm not touching this gamemode at all now, I want to have fun, not spend hours looking for a needle in a haystack!
