There should be a feature where if your team has already blew up one bomb on Rush, and the next one has already been planted, even if you run out of tickets you still have a chance to win. It will be like a sudden death where if your tickets are at zero, but you already had planted the bomb you could still win. But if the enemy defuses the bomb, you immediately lose. Also the sudden death would mean that once you die you can't respawn. But the defenders could still respawn. It would only work in the attackers favor if they had just locked down the site with like 15 players and the bomb was just about to blow. Most scenarios will still lean in the defenders favor.
