A common trend at the moment is to gift everyone in the team caretakers to build a super.
If you set the caretaker to build and then gift it, it will continue to build the super.
This is fine when the team has a good metal income, but when each player has <10m/s it completely stalls your building of everything else.
Pretty sure if you also set the super to high priority it will affect everyone helping as well.
As far as I can see this has lead to a lot more ridiculously early super rushes in recent big teams games, <20min Zenith for example, especially on high metal maps where it is possible to rush a super in like 3min.
