Continuing the discussion from Overwatch PTR Patch Notes – June 28, 2018:
Maybe it would be better to change the mechanic to fix time instead of additional time (for all game modes). In QP you don’t get the second round (or even additional attempts) to even out a quick first point. This would help the defender and give them always the same condition. While the attacker not losing much, if they are strong then they should be able to take the second point quick too, if they need the full time then it is still the same as with additional time.
