Half Comeback Mechanic
The Half Comeback Mechanic always occurs when a team is one point behind at the capture phase.
This team receives 3.9% every other tick while capturing. The team in the lead receives regular 3% per tick.
After the first push
If the opponents captured the first objective (0:1) and now seem to push the payload through in the first round, then it would make more sense not to use ultimates to stop the opponents. Using the Full Comeback Mechanic (0:2) and the saved Ultimates the own team should capture the next capture point and get a chance to turn the fight with the earned knowledge about the opponents.
During the game
After your team has captured the point (2:3) and now seem to push through, then it would make more sense not to waste any ultimates. After the successful opponent's defense, the score is still 2:3 for the opponents. Using the comeback mechanic and the saved ultimates the own team should capture the next capture point (3:3) and can now try to win the game (4:3).
Outplay the enemy team with Credits advantages
Succesfully taking the capture point gives each teammate 300 credits.
That makes 1,500 credits for the team's credits pool. Using these credits, the team can better adapt to the opposing team by buying items.
To increase the probability of a successful capture, a team can take advantage of the comeback mechanic. After the team is 0:2 behind, the comeback mechanic starts. If the team captures the second objective, but doesn't make the conversion, the score is 1:3. The team still has full use of the Comeback mechanics and has a high chance to take the point again (2:3). Depending on the course of the game, the payload can be pushed through or the weakened comeback mechanics can be used for the next point fight.
