This gives defenders a chance to build up points in advance, where to fall back too if its to late for them to get on point etc but also lets attackers know the objective, just like they were getting briefed before being deployed
That’s not good. It would only mean that defenders will be short on bodies at the current active objectives.
If anything, once the objective is conquered. There should be some time in which the greyzone doesn’t change and in which the defenders can fortify their new objective.
they could also use lock mechanism just like in confrontation. extra 30 seconds or 1 minute without fear of being overrun would be good for people going back to build rallies and to build up defenses in cap.
